4\left(x-2\right)-3\left(2x-3\right)=12x-12
Multiply both sides of the equation by 12, the least common multiple of 3,4.
4x-8-3\left(2x-3\right)=12x-12
Use the distributive property to multiply 4 by x-2.
4x-8-6x+9=12x-12
Use the distributive property to multiply -3 by 2x-3.
-2x-8+9=12x-12
Combine 4x and -6x to get -2x.
-2x+1=12x-12
Add -8 and 9 to get 1.
-2x+1-12x=-12
Subtract 12x from both sides.
-14x+1=-12
Combine -2x and -12x to get -14x.
-14x=-12-1
Subtract 1 from both sides.
-14x=-13
Subtract 1 from -12 to get -13.
x=\frac{-13}{-14}
Divide both sides by -14.
x=\frac{13}{14}
Fraction \frac{-13}{-14} can be simplified to \frac{13}{14} by removing the negative sign from both the numerator and the denominator.
