-7u+4u-12<-33
Use the distributive property to multiply 4 by u-3.
-3u-12<-33
Combine -7u and 4u to get -3u.
-3u<-33+12
Add 12 to both sides.
-3u<-21
Add -33 and 12 to get -21.
u>\frac{-21}{-3}
Divide both sides by -3. Since -3 is negative, the inequality direction is changed.
u>7
Divide -21 by -3 to get 7.
