8x+5+12=6x+15
Multiply both sides of the equation by 3.
8x+17=6x+15
Add 5 and 12 to get 17.
8x+17-6x=15
Subtract 6x from both sides.
2x+17=15
Combine 8x and -6x to get 2x.
2x=15-17
Subtract 17 from both sides.
2x=-2
Subtract 17 from 15 to get -2.
x=\frac{-2}{2}
Divide both sides by 2.
x=-1
Divide -2 by 2 to get -1.
