solve in pieces:
1. solve 5x+2 <= -18 for x<=-4
2. 2x+1>21 gives x>10
3. recombine for the answer: x<=-4 or x=10
on a number line, this means x is a hollow dot at 10 and solid line over all numbers greater than 10, and a solid dot at -4 and solid line over all numbers less than -4
hope this helps
if you ever have problems, always break the question down as small as it can go and make it manigible

Do your own homework - you'll never learn if someone else does it, and that won't help you any on your test.
