Answer 9

well...
greater then (>)
less then (<)

examples :
at least 20 would be > 20
at most 20 would be < 20

I do not know how else to explain the set up process without having a problem in front of me.
=======================
examples :
| 2x + 3 | < 6 .....if it is less then, it is set up like this :
-6 < 2x + 3 < 6
and then you solve from here.

| 2x + 3 } > 6....if it is greater then, it is set up like this :
2x + 3 > 6 and 2x + 3 < -6
and then you solve both
