-9x+12+3=25+x
Combine -4x and -5x to get -9x.
-9x+15=25+x
Add 12 and 3 to get 15.
-9x+15-x=25
Subtract x from both sides.
-10x+15=25
Combine -9x and -x to get -10x.
-10x=25-15
Subtract 15 from both sides.
-10x=10
Subtract 15 from 25 to get 10.
x=\frac{10}{-10}
Divide both sides by -10.
x=-1
Divide 10 by -10 to get -1.
