Hi John fran kennedi,
This question can actually be solved with a bit of "brute force"; I'm going to give you some hints, then let you try it out to see how quickly you can solve it.
The question asks how many INTEGERS that are LESS THAN 5 fit the given inequality? From the answer choices, there is at least 1 and no more than 5 possible answers. Given the limitation that ALL of the answers are less than 5, how long would it take you to find them all?
Here's a suggestion:
-What happens when you plug in 4?
-What happens when you plug in 3?
Can you spot a pattern when you do this work?
Etc.

In a pinch, the easiest way is to try 0, 1, 2, 3, and 4, then some negatives to see what's happening.
With a little more time, you want to consider two cases: what happens if (x - 2) > 0 and what happens if 0 > (x - 2). Multiplying both sides of the inequality by (x - 2) will then give you two different sets of solution, and you can roll from there.
