D. x - 5 = 4 or x - 5 = -4
E. 2x + 3 > 4 or 2x + 3 < -4

Answer 1

Use what we've already talked about...since it's > 4, it is going *away* from 0...

Answer 2

so it would be C

Answer 3

C is *towards* 0...which one is *away* from 0?

Answer 4

it wouldnt be a,b, or d.... so it has to be E

Answer 5

There you go! :) Now you've got it.

Answer 6

Remember...if it's *away* (>) you'll get 2 disjoint sets (the answer will have two inequalities and the word "or"). If it's *towards* (<) you'll get one comined inequality.

Other than that, you're now a master at this.
