The compound inequality is:

To find:
The integer solutions for the given compound inequality.
Solution:
We have,

Case 1: 


...(i)
Case 2: 

...(ii)
Using (i) and (ii), we get

The integer values which satisfy this inequality are only 3 and 4.
Therefore, the integer solutions to the given inequality are 3 and 4.
The answer is any whole number larger than 3
