Answer 7

Now add 450 both sides & then divide -20 both sides :)

Answer 8

Nw to solve this inequality u hav to isolate x.
To do that plz perform the following steps.
1.Add 9 to both sides.
2.Multiply both sides by 5.
3.Divide by -2 both sides.
When u divide by a negative number the inequality sign flips.
see if u can do it:)
