2x-3x+12+5=2-2\left(3-4x\right)
Use the distributive property to multiply -3 by x-4.
-x+12+5=2-2\left(3-4x\right)
Combine 2x and -3x to get -x.
-x+17=2-2\left(3-4x\right)
Add 12 and 5 to get 17.
-x+17=2-6+8x
Use the distributive property to multiply -2 by 3-4x.
-x+17=-4+8x
Subtract 6 from 2 to get -4.
-x+17-8x=-4
Subtract 8x from both sides.
-9x+17=-4
Combine -x and -8x to get -9x.
-9x=-4-17
Subtract 17 from both sides.
-9x=-21
Subtract 17 from -4 to get -21.
x=\frac{-21}{-9}
Divide both sides by -9.
x=\frac{7}{3}
Reduce the fraction \frac{-21}{-9} to lowest terms by extracting and canceling out -3.
