Question

Please help me understand this?! Will fan and give medal!

Answer 1

Solve for x: −2x + 5 < 7

x > −1

x < −1

x > −6

x < −6

Answer 2

First you want to get X by its self, so you would add a positive 2 to make the equation X + 5< 7, then the equation would be 5X < 7 and like before, you want X by its self so to get rid of +5 you subtract -5 to get X < 7.

Answer 3

i think

Answer 4

@VickySkittles you have the right idea, but you need to time x by -2.
