-2x+8-15=16+8x-2-3
Combine 2x and -4x to get -2x.
-2x-7=16+8x-2-3
Subtract 15 from 8 to get -7.
-2x-7=14+8x-3
Subtract 2 from 16 to get 14.
-2x-7=11+8x
Subtract 3 from 14 to get 11.
-2x-7-8x=11
Subtract 8x from both sides.
-10x-7=11
Combine -2x and -8x to get -10x.
-10x=11+7
Add 7 to both sides.
-10x=18
Add 11 and 7 to get 18.
x=\frac{18}{-10}
Divide both sides by -10.
x=-\frac{9}{5}
Reduce the fraction \frac{18}{-10} to lowest terms by extracting and canceling out 2.
