4u+24+3u\leq -32
Add 3u to both sides.
7u+24\leq -32
Combine 4u and 3u to get 7u.
7u\leq -32-24
Subtract 24 from both sides.
7u\leq -56
Subtract 24 from -32 to get -56.
u\leq \frac{-56}{7}
Divide both sides by 7. Since 7 is positive, the inequality direction remains the same.
u\leq -8
Divide -56 by 7 to get -8.
