Solve by the elimination method.
7r-9s= -58
9r+7s=74
I know that I need to multiply the first equation by 9 and the second equation by 7.
The equations look like this:
63r-81s= -522
63r+49s=518
Thanks.

subtract

0r-130s=-1040

But how would I solve for r?
s=8 does that mean r=0?
Thanks.

Never mind I got the answer for r.
Thanks.
