1. Constant
Variables
The picture above represents the equation
3x + 1 = 2x + 2

2. To solve the equation we want to remove the
variables on the right.
3x + 1 = 2x + 2
-2x

3. To keep the equation balanced we have to do the
same on the left.
3x + 1 = 2x + 2
-2x -2x
1x + 1 = 2

4. Now we want to get rid of the constant on the left
side.
3x + 1 = 2x + 2
-2x -2x
1x + 1 = 2
-1

5. To keep the equation balanced we do the same on
the right side.
3x + 1 = 2x + 2
-2x -2x
1x + 1 = 2
-1 -1

6. We have solved for x and kept our equation
balanced.
3x + 1 = 2x + 2
-2x -2x
1x + 1 = 2
-1 -1
1x =1

7. 5x + x = 8 + 4x
4x + 5 = 2x + 13
3x + 4 = 6x + 1
4x + 4 = 5x = 1
