9x-36-5x=x-12
Use the distributive property to multiply 9 by x-4.
4x-36=x-12
Combine 9x and -5x to get 4x.
4x-36-x=-12
Subtract x from both sides.
3x-36=-12
Combine 4x and -x to get 3x.
3x=-12+36
Add 36 to both sides.
3x=24
Add -12 and 36 to get 24.
x=\frac{24}{3}
Divide both sides by 3.
x=8
Divide 24 by 3 to get 8.
