|4x + 9|> -2
There are two inequalities to be solved.
4x + 9 > -2 and -(4x + 9) > -2
4x + 9 > -2
Subtract 9 from both sides.
4x > -2 - 9
4x > -11
Divide both sides by 4.
x > -11/4
-4x-9 > -2
Add 9 to both sides.
-4x > -2 + 9
-4x > 7
Divide both sides by -4. This will reverse the inequality.
x < -7/4
Solutions for x
x > -11/4
x < -7/4
Since x>-11/4 and x<-7/4 overlap, all values for x are valid answers.
