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.

I think you are totally wrong.
Take the last one.
x+2y=9
here are some equivalent equations:
2y9=x
x+9=2y
14y=63+7x
Equivalent equations are equations that have the same solution.
