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
