Treat these as if they were equations but keeping the in-equality sign instead of the equal sign,
EXCEPT
when you multiply or divide the in-equation by a negative, you must reverse the inequality sign.

e.g.
last one:

-8x > -64
I would have to divide by -8 to get +x , so
x < 8

1st one:
x + 8 < -28
x < -28 - 8 , I did not multiply/divide so no big deal
x < -36

you do #2, let me know what you get
