|2x-5| is greater than-3 and |2x-5| is less than -3
----
Note: Absolute value expressions cannot be negative.
---
If |2x-5| > -3 it must be >= 0
----
|2x-5| >= 0 for all Real Numbers

The other tutor apparently thought the second one was 
greater, but it was less

|2x-5| < -3

Absolute values are always either positive or 0.
So it would be impossible for |2x-5| to be less than
-3, for to do so, it would have to be negative, and 
it is impossible for an absolute value to be negative.

So that one would have no solutions.
