-42+6x-8=8\left(x+5\right)-12
Use the distributive property to multiply -6 by 7-x.
-50+6x=8\left(x+5\right)-12
Subtract 8 from -42 to get -50.
-50+6x=8x+40-12
Use the distributive property to multiply 8 by x+5.
-50+6x=8x+28
Subtract 12 from 40 to get 28.
-50+6x-8x=28
Subtract 8x from both sides.
-50-2x=28
Combine 6x and -8x to get -2x.
-2x=28+50
Add 50 to both sides.
-2x=78
Add 28 and 50 to get 78.
x=\frac{78}{-2}
Divide both sides by -2.
x=-39
Divide 78 by -2 to get -39.
