Answer by Alan3354(69443) (Show Source): You can put this solution on YOUR website!
5x+y=-9 x2 --> 10x+2y = -18
3x+2y=3
10x+2y = -18
-------------Subtract
-7x = 21
x = -3
---------
Sub into 2nd eqn
3(-3) + 2y = 3
-9 + 2y = 3
2y = 12
y = 6
-------
You'll have to do the graphs.

Ignore that other "tutor", he's a child that appears with an inane comment now and then.
