-2\left(3x+2-x-4\right)=-3\left(x-3\right)
Variable x cannot be equal to 3 since division by zero is not defined. Multiply both sides of the equation by 2\left(x-3\right), the least common multiple of x+2-2x+1,2.
-2\left(2x+2-4\right)=-3\left(x-3\right)
Combine 3x and -x to get 2x.
-2\left(2x-2\right)=-3\left(x-3\right)
Subtract 4 from 2 to get -2.
-4x+4=-3\left(x-3\right)
Use the distributive property to multiply -2 by 2x-2.
-4x+4=-3x+9
Use the distributive property to multiply -3 by x-3.
-4x+4+3x=9
Add 3x to both sides.
-x+4=9
Combine -4x and 3x to get -x.
-x=9-4
Subtract 4 from both sides.
-x=5
Subtract 4 from 9 to get 5.
x=-5
Multiply both sides by -1.
