7y+8\leq -2y-64
Use the distributive property to multiply -2 by y+32.
7y+8+2y\leq -64
Add 2y to both sides.
9y+8\leq -64
Combine 7y and 2y to get 9y.
9y\leq -64-8
Subtract 8 from both sides.
9y\leq -72
Subtract 8 from -64 to get -72.
y\leq \frac{-72}{9}
Divide both sides by 9. Since 9 is positive, the inequality direction remains the same.
y\leq -8
Divide -72 by 9 to get -8.
