–18 < 4x – 2 <= 30
~~~~~~~~~~~~~~~~~~~~~~~~~~~ 

Add 2 to all three parts (left, middle and right parts) of your compound inequality. 

You will get an equivalent inequality

-16 < 4x <= 32.


Next divide all three parts by 4.

You will get an equivalent inequality

-4 < x <= 8.


It is your final answer.
