Question
Damon,
Thanks for the help. Let me see if I get it now. So,
-2x < -4
divide both sides by -2
answer is x > 2
I had x < 2, but I reverse the sign since I divided by a -2 on both sides, correct?

Hi, I am not a teacher but I know this stuff.
You are correct.
When multiplying or dividing by neg number you always reverse the sign.
