So, I've got these other sets of problems, that are telling me to write equivilant equations for the equations given, heres what I think.

1) x+y=-10

-5+5=10

-5(2)+10

2) 5x+10y=15

5x(3)=15

5x+10=15

3)-x+2y=9

y=3(3)=9

3+6=9

Heres what I need YOU tutors to help me with:

Could you tell me if my answers are correct, if not explain why?

Thank you.
