a - b = 2
a + b = 4
So, a = 3
b = 1
a + b = 4
So, a = 3
b = 1

Now , the equation will be
a-b=2......(1)
a+b=4....(2)
Adding eq 1&2, we get
a-b=2
a+b=4
2a=6
a=3
putting the value of a in eq1
a-b=2
3-b=2
-b=2-3
-b=-1
b=1
here the value of a=2 b=1
a-b=2......(1)
a+b=4....(2)
Adding eq 1&2, we get
a-b=2
a+b=4
2a=6
a=3
putting the value of a in eq1
a-b=2
3-b=2
-b=2-3
-b=-1
b=1
here the value of a=2 b=1
