You can put this solution on YOUR website!
-2x+%2B+y+%2B+6+=+0
-2x+=+-y+-+6
2x+=+y+%2B+6 remember this!
2x+%2B+y+-+8+=+0 now plug the value for 2x from the equation above into this equation
%28y%2B6%29+%2B+y+-+8+=+0
2y+-2+=+0 and x is gone. You can solve for y now if you wish, but the problem only asked you to eliminate x

Add the two equations together
-2x + 2x + y + y + 6 - 8 = 0
The resulting equation is
2y - 2 = 0
...
Solving for y
2y = 2
y = 1
