Question

Can someone explain the steps to working this problem: -11<-4x+5<13?

Answer 1

There are two parts to this:
-11<-4x+5 and -4x+5<13
1) -11<-4x+5
-16<-4x (Subtract both sides by 5)
4>x (Divide both sides by -4)
2) -4x+5<13
-4x<8 (Subtract both sides by 5)
x>-2 (Divide both sides by -4)

Answer 2

Thanks!

Question: So why would you express that answer as -2>x>4?

Answer 4

-2>x>4 not this

-2<x<4 It is like this.
