15-27+3x=x
Use the distributive property to multiply -3 by 9-x.
-12+3x=x
Subtract 27 from 15 to get -12.
-12+3x-x=0
Subtract x from both sides.
-12+2x=0
Combine 3x and -x to get 2x.
2x=12
Add 12 to both sides. Anything plus zero gives itself.
x=\frac{12}{2}
Divide both sides by 2.
x=6
Divide 12 by 2 to get 6.
