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