Homework Help: math

Posted by Holly on Saturday, March 13, 2010 at 7:19pm.

Can someone help me solve the following....using elimination methods

1)
5x+7y=43
-4x+y=25

2)9x-9y=36
7y-3x=-14

I think the answers are
would the answer to number 1 be
(-4.26,1.52)?

would the answer to number 2 be

(-0.5,-6.5)?
Can someone please verify or tell me what I did wrong if they are not right!

Thanks
