2x%2By=6


x|y
-1|8 ..........given x=-1..->....2%2A%28-1%29%2By=6....->....y=6%2B2=8
1|4 ..........given x=1..->.....2%2A%281%29%2By=6....->....y=6-2=4
2|2 ..........given x=2..->.....2%2A%282%29%2By=6.->.y=6-4=2
2|2 ..........given y=2..->...2x%2B2=6.->.2x=6-2, x=4%2F2=2
4|-2..........given y=-2..->..2x-2=6.->.2x=6%2B2, x=8%2F2=4
