x+12=3x-18
Use the distributive property to multiply 3 by x-6.
x+12-3x=-18
Subtract 3x from both sides.
-2x+12=-18
Combine x and -3x to get -2x.
-2x=-18-12
Subtract 12 from both sides.
-2x=-30
Subtract 12 from -18 to get -30.
x=\frac{-30}{-2}
Divide both sides by -2.
x=15
Divide -30 by -2 to get 15.
