You can put this solution on YOUR website!
x + y = 2 ---------(1)
x - y = 6 ---------(2)
Subtracting (2) from (1) we get
2y = 2 - 6 = -4
y = -2

I am stuck on correct answer for:
'
If x + y = 2...................1
and x - y = 6..........................2
EQN.I - EQN.2
X+Y - (X-Y) = 2-6= -4
X+Y - X + Y =-4
2Y = -4
then y = -4/2 =-2
