4\left(x-2\right)-6\left(12-x\right)=3\left(5x-36\right)-12
Multiply both sides of the equation by 12, the least common multiple of 3,2,4.
4x-8-6\left(12-x\right)=3\left(5x-36\right)-12
Use the distributive property to multiply 4 by x-2.
4x-8-72+6x=3\left(5x-36\right)-12
Use the distributive property to multiply -6 by 12-x.
4x-80+6x=3\left(5x-36\right)-12
Subtract 72 from -8 to get -80.
10x-80=3\left(5x-36\right)-12
Combine 4x and 6x to get 10x.
10x-80=15x-108-12
Use the distributive property to multiply 3 by 5x-36.
10x-80=15x-120
Subtract 12 from -108 to get -120.
10x-80-15x=-120
Subtract 15x from both sides.
-5x-80=-120
Combine 10x and -15x to get -5x.
-5x=-120+80
Add 80 to both sides.
-5x=-40
Add -120 and 80 to get -40.
x=\frac{-40}{-5}
Divide both sides by -5.
x=8
Divide -40 by -5 to get 8.
