Answer 6

but dont you switch the signs?

Answer 7

switch the signs when multiplying or dividing by a negative number and when you bring the signs over to the other side.

Answer 8

ok, so the answer is y>-36

Answer 9

yes

Answer 10

-y<36
y>-36

Answer 11

Thank you guys so so so so so so much!

Answer 12

@completeidiot thanku for letting me know where I went wrong.

Answer 13

now for the explanation

lets say y=1

that would mean
-1<36

now if we multiplied both sides by -1

we would get 1<-36
this is obviously incorrect, which is the reason why switching the sign is important

Answer 14

-y < 36

add y to both sides; subtract 36 from both sides:
-36 < y

Answer 15

Divide -1 both sides & reverse the inequality sign :)

Answer 16

got it
