4\left(x-2\right)-3\left(x-1\right)=6\left(x-3\right)-12
Multiply both sides of the equation by 12, the least common multiple of 3,4,2.
4x-8-3\left(x-1\right)=6\left(x-3\right)-12
Use the distributive property to multiply 4 by x-2.
4x-8-3x+3=6\left(x-3\right)-12
Use the distributive property to multiply -3 by x-1.
x-8+3=6\left(x-3\right)-12
Combine 4x and -3x to get x.
x-5=6\left(x-3\right)-12
Add -8 and 3 to get -5.
x-5=6x-18-12
Use the distributive property to multiply 6 by x-3.
x-5=6x-30
Subtract 12 from -18 to get -30.
x-5-6x=-30
Subtract 6x from both sides.
-5x-5=-30
Combine x and -6x to get -5x.
-5x=-30+5
Add 5 to both sides.
-5x=-25
Add -30 and 5 to get -25.
x=\frac{-25}{-5}
Divide both sides by -5.
x=5
Divide -25 by -5 to get 5.
