15\left(-\frac{y}{3}+6\right)+6y=57
Multiply both sides of the equation by 3.
15\left(-\frac{y}{3}\right)+90+6y=57
Use the distributive property to multiply 15 by -\frac{y}{3}+6.
-5y+90+6y=57
Cancel out 3, the greatest common factor in 15 and 3.
y+90=57
Combine -5y and 6y to get y.
y=57-90
Subtract 90 from both sides.
y=-33
Subtract 90 from 57 to get -33.
