Answer by solver91311(24713) (Show Source): You can put this solution on YOUR website!
I'll do the first one, and then you can follow the process to do the others:
Distribute and remove parentheses:
Collect like terms:
Add -4h to both sides:
Add 79 to both sides:
Multiply both sides by -1. Since you are multiplying across an inequaltity by a negative number, you must reverse the sense of the inequality.
Done.
Check the answer:
Pick something smaller than -79, like -80.
, so something smaller works, now we have to check that something slightly larger DOESN'T work:
is a false statement. Answer checks
