Ms Sue has provided some but not all possible values of x.

First assume 2x-3 >0

This requires x > 1.5, and

2x-3 < 7

That means x < 5.

Therefore 1.5 < x < 5 are answers.

If 2x < 3, which means x < 1.5,

3 - 2x < 7

x > -2

Therefore -2 < x < 1.5 are answers

Put them together and you find that -2 < x < 5 is the range of answers.
