x + y = 5
=> let x be = 4
and y = 1
=> 4 + 1 = 5
5 = 5
L.H.S = R.H.S
Hence proved
and
4 - 1 = 3
3 = 3
L.H.S = R.H.S
Hence proved

x+y=5 -(i)
x-y=3 -(ii)
From (i),
x=5-y
Substitute this value of x in (ii)
(5-y)-y=3
5-y-y=3
5-2y=3
-2y=3-5
-2y=-2
2y=2
y=
Use value of y in (i)
x+1=5
x=5-1
Therefore, value of x=4 and y=1
