Treat these as if they were equations but keeping the inequality sign instead of the equal sign,
EXCEPT
when you multiply or divide the inequation 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
