Answer:
s>-3
Step-by-step explanation:
1) distribute -4(3s+4)<20: -12s-16<20
2) combine like numbers by adding 16 to the both sides:
-12s-16+16<20+16
= -12s<36
3) divide -12 on both sides to isolate the variable s
-12s/-12<-36/-12
4) since it is being divided by a negative number, the inequality sign flips from < to >
Answer:
s>-3
