18x - 6x = 144
12x = 144
12x / 12 = 144 / 12
x = 12

To solve for x:
18x - 6x = 144
12x = 144
x = 144/12
x = 12
-good luck-

18x-6x = 12x
so you have 12x=144
divide both sides by 12 and you get x=12

18x - 6x = 144
Therefore,
12x = 144
x = 12
If you backtrack the answer,
18(12) - 6(12) = 144
216 - 72 = 144
Therefore, x = 12.
