Answer 1

isn't zigzagoon a lame pokemon?

Answer 2

Pssh, he has a pretty cool name though. Is it possible for you to help me with this?

Answer 3

Well, you have that\[\frac x5\geqslant-2.\]This means that\[x\geqslant-10,\]because we multiply both sides of the inequality by \(5\).

Answer 4

Alright, I think I get it. It's been a while since I've done this type of math but it seems to be coming back.
