24-x-2x+12=3x
Add 12 and 12 to get 24.
24-3x+12=3x
Combine -x and -2x to get -3x.
36-3x=3x
Add 24 and 12 to get 36.
36-3x-3x=0
Subtract 3x from both sides.
36-6x=0
Combine -3x and -3x to get -6x.
-6x=-36
Subtract 36 from both sides. Anything subtracted from zero gives its negation.
x=\frac{-36}{-6}
Divide both sides by -6.
x=6
Divide -36 by -6 to get 6.
