Follow this example and the steps used to solve this simple equation with unknowns on both sides.
Example
3x - 4 = 5x - 20
Method
Reverse so that the bigger x term is on the left (this move is optional but makes it easier)
5x - 20 = 3x - 4
Subtract 3x from both sides:
2x - 20 = -4
Add 20 to both sides:
2x = 16
Divide both sides by 2:
x = 8
Check answer
Substitute x = 8 into the original equation 3x - 4 = 5x - 20
Left-hand side = 3 x 8 - 4 = 24 - 4 = 20
Right-hand side = 5 x 8 - 20 = 40 - 20 = 20
