x-2

---- > 2x+7

3

X < -7, according to the back of the book, but how do I get to that?

You solve it like a normal equation, with a small caveat: when you multiply both sides by -1, the inequality sign flips.

x - 2 > 3 (2x + 7)

x > 6x + 21 + 2

x - 6x > 23

-5x > 23

x < - 23 / 5

That's not -7... that's more like -4.(something)
