12x - 28 = 18x - 88Put the variables on one side and the constants on the other by subtracting 12x from both sides and adding 88 to both sides.
12x - 12x - 28 + 88 = 18x - 12x - 88 + 88
Simplify
60 = 6x
Divide both sides by 6
x = 10
If you want to check your answer, which is always a good idea, plug in 10 for x in the original expression and see if you get a true statement:
12(10) - 28 = 18(10) - 88
120 - 28 = 180 - 88
