2x+y=6
X+y=6/2
X=3-y. (eq. 1)
again,
2x-y=2.
2(3-y)-y=2(from eq.1)
6-2y-y=2
6-3y=2
6-2=3y
4=3y
4/3=y
now find y and then follow eq.1 and u will find the answer
X+y=6/2
X=3-y. (eq. 1)
again,
2x-y=2.
2(3-y)-y=2(from eq.1)
6-2y-y=2
6-3y=2
6-2=3y
4=3y
4/3=y
now find y and then follow eq.1 and u will find the answer

2x + y =6
2x - y =2
Adding these two equations together
4x = 8
So x=2
Substituting x in the dirst equation,
4+ y=6
So y=2
So x = y = 2
2x - y =2
Adding these two equations together
4x = 8
So x=2
Substituting x in the dirst equation,
4+ y=6
So y=2
So x = y = 2
