Can someone please help with this problem?

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

After this I get confused. Could someone please help?

Thanks.
