If 3x+4y=7 and 2y=6x+6, then what is xy?(adsbygoogle = window.adsbygoogle || []).push({});

3X+4y=7

-6X+2y=6

(2)3X+4y=7 which goes to 6X+8Y=14

I cross the X out, subtract and get 6y=8

then I got 4/3

and final answer i got was 20/3

HOWEVER, the answer says is is -2/3 ... I don't understand how that is the answer...

Please Help!
