5x+15-6x-6=9-10\left(2x-4\right)+3x-12+2
Use the distributive property to multiply -6 by x+1.
-x+15-6=9-10\left(2x-4\right)+3x-12+2
Combine 5x and -6x to get -x.
-x+9=9-10\left(2x-4\right)+3x-12+2
Subtract 6 from 15 to get 9.
-x+9=9-20x+40+3x-12+2
Use the distributive property to multiply -10 by 2x-4.
-x+9=49-20x+3x-12+2
Add 9 and 40 to get 49.
-x+9=49-17x-12+2
Combine -20x and 3x to get -17x.
-x+9=37-17x+2
Subtract 12 from 49 to get 37.
-x+9=39-17x
Add 37 and 2 to get 39.
-x+9+17x=39
Add 17x to both sides.
16x+9=39
Combine -x and 17x to get 16x.
16x=39-9
Subtract 9 from both sides.
16x=30
Subtract 9 from 39 to get 30.
x=\frac{30}{16}
Divide both sides by 16.
x=\frac{15}{8}
Reduce the fraction \frac{30}{16} to lowest terms by extracting and canceling out 2.
