-3x+12=9x
Use the distributive property to multiply -3 by x-4.
-3x+12-9x=0
Subtract 9x from both sides.
-12x+12=0
Combine -3x and -9x to get -12x.
-12x=-12
Subtract 12 from both sides. Anything subtracted from zero gives its negation.
x=\frac{-12}{-12}
Divide both sides by -12.
x=1
Divide -12 by -12 to get 1.
