6\left(2x-3\right)-12x=4\left(3-x\right)+3\left(3x-2\right)
Multiply both sides of the equation by 12, the least common multiple of 2,3,4.
12x-18-12x=4\left(3-x\right)+3\left(3x-2\right)
Use the distributive property to multiply 6 by 2x-3.
-18=4\left(3-x\right)+3\left(3x-2\right)
Combine 12x and -12x to get 0.
-18=12-4x+3\left(3x-2\right)
Use the distributive property to multiply 4 by 3-x.
-18=12-4x+9x-6
Use the distributive property to multiply 3 by 3x-2.
-18=12+5x-6
Combine -4x and 9x to get 5x.
-18=6+5x
Subtract 6 from 12 to get 6.
6+5x=-18
Swap sides so that all variable terms are on the left hand side.
5x=-18-6
Subtract 6 from both sides.
5x=-24
Subtract 6 from -18 to get -24.
x=\frac{-24}{5}
Divide both sides by 5.
x=-\frac{24}{5}
Fraction \frac{-24}{5} can be rewritten as -\frac{24}{5} by extracting the negative sign.
