Linear Equations with Variables on Both Sides

Linear equations with variables on both sides are equations that have variables on both sides of the equal sign. These types of equations can be challenging to solve because the variable is not isolated on one side of the equation.

Concept of Variables on Both Sides

In equations with variables on both sides, the variable appears on both sides of the equation. For example, in the equation 2x + 3 = x + 7, the variable x appears on both sides of the equation. To solve this type of equation, it is necessary to isolate the variable on one side of the equation.

Isolating the Variable

Isolating the variable means moving all the terms containing the variable to one side of the equation and all the constants to the other side. This process allows the variable to be solved for. It is important to isolate the variable because it helps to simplify the equation and makes it easier to solve.

To isolate the variable, it is necessary to use inverse operations to undo any operations that are being performed on the variable. For example, if the variable is being added to both sides of the equation, it can be isolated by subtracting the variable from both sides.

It is essential to keep the equation balanced by performing the same operation on both sides of the equation. For example, if 2 is added to one side of the equation, 2 must also be added to the other side of the equation to keep it balanced.

In conclusion, understanding how to solve linear equations with variables on both sides is an essential skill in algebra. By isolating the variable and keeping the equation balanced, it is possible to solve these types of equations.

Equations with Variables on Both Sides Word Problems

Word problems are a common way to test a student’s understanding of equations with variables on both sides. These types of problems can be tricky, but with practice, students can become proficient in solving them.

When solving word problems with variables on both sides, it is important to remember that the goal is to isolate the variable on one side of the equation. This is typically done by using the properties of equality to move variables from one side to the other.

To help students understand how to solve equations with variables on both sides, teachers often use real-world scenarios to create word problems. For example, a problem might ask how long it will take two leaking containers to have the same amount of water if one container has a leak rate of 6 ml per minute and the other has a leak rate of 10 ml per minute.

To solve this problem, students would need to write an equation that represents the situation, such as:

800 – 6x = 1000 – 10x

Where x represents the number of minutes it takes for the containers to have the same amount of water. From here, students would use the properties of equality to isolate the variable, x, on one side of the equation.

Another common type of word problem with variables on both sides involves distance, rate, and time. For example, a problem might ask how long it takes two runners to meet if one runner is running at a speed of 6 miles per hour and the other is running at a speed of 8 miles per hour.

To solve this problem, students would need to write an equation that represents the situation, such as:

6x + 6 = 8x

Video Transcript:

In this video we’re gonna work on some solving equations with variables on both sides practice problems from our solving equations with variables on both sides worksheets. Let’s jump to number one. Our first problem on our how to solve equations with variables on both sides worksheet gives us 4x minus 19 equals x plus 11. The first step in solving this equation with variables on both sides is to get all the constants on one side together.

What we need to do is we need to add 19 here to this side plus 19 that the constant on this side will go away and that we have the constants on the same side together or only on one side. After we add 19 here the 19’s cancel and we bring down the 4 x on this side and we bring down the X on this side and then we’re going to combine 11 plus 19 which is 30. Then the next step is we need to get the variable on the same side together. In order to do that we need to subtract the X here and the reason we’re subtracting X is because we have to get the variables on the opposite side of the constant.

If we subtracted 4x and put the 4x over here that wouldn’t work because they would be on the same side of the equal sign and we don’t want to do that we want to get the X or we want to get the variables on the opposite side of the equal sign. After you subtract this X to get rid of this X here. This X goes away we have 4 X minus 1 X which is 3 X. On this side and then we have 30 on this side. This 3x is like saying 3 times X. In order to get rid of this coefficient you have to divide by 3 because the opposite of 3 times something is to divide that same number by 3. We will divide this by three the X the threes cancel and you’re left with just X on this side and then a 30 divided by 3 is 10. Our solution to our first equation with variables on both sides is x equals 10.

Alright moving on to our next problem, which is number two on our solving equations variables on both sides worksheet. We have 2x minus 3 equals 11x minus 21. In this case the first thing we need to do is we need to get the constants on the same side together. In order to do that I’m going to add 3 here so that the constant on this side of the equal sign will go away. We use positive 3 because this is minus 3 they will cancel and you’re left with 2x on this side and then you bring down your 11x here and then negative 21 plus 3 is negative 18.

The next step is to get rid of this 11x so we have to subtract 11x here, and once again the reason we’re subtracting 11x is because we have to get the X’s or the variables on one side of the equals sign and the constants on the other side of the equals sign. We subtract 11x here when you subtract 11x these X’s cancel 2x minus 9x is, I’m sorry 2x minus 11x, is negative 9x equals and then you bring down your negative 18 on this side. The last step is to divide both sides by negative 9 because the coefficient is negative 9. We have to cancel that out so you divide this side by negative 9. The negative 9s cancel and you’re left with on this side negative 18 divided by negative 9 which is positive 2. This is the second example of how to do equations with variables on both sides.

The last problem we’re going to work on on our multi step equations with variables on both sides worksheet is number five. Number five gives us 3x minus 53 equals 5x plus 13. The first step in solving this problem is to get all the constants on the same side together. We’re going to go ahead and add 53 here so that these guys will cancel and you’ll be left with 3x on this side and then you bring your 5x straight down and then 13 plus 53 is 66. Our next step is to get the variables on the opposite side of the constants.

We’re going to subtract 5x here the 5x is canceled and you have 3x minus 5x which is negative 2 x equals 66 on this side. Then your final step is to get rid of this negative 2. We have to divide this side by negative 2 whatever you do to one side you do to the other. We divide over here by negative 2 these guys cancel you’re left with just x equals 60 6 divided by negative 2 which is negative 33. That is our solution to our last problem in our equations with variable on both sides worksheet and download the solving equations with variables on both sides notes for more practice.
