Question

If x = a, y = b is the solution of the equations x - y = 2 and x + y = 4, then the
of a and bare, respectively
3 and 5
(B) 5 and 3
(C) 3 and 1
(D) -1 and -3​

Answer 1

Step-by-step explanation:

Hai friends,

Here is ur ans;

Let x=a , y=b ,

Then , a-b=2.... (1)

, a+b=4.... (2)

Adding eqn (1) and (2) ,

2a=6

a=6/2

a=3

Substitute the value of "a" in eqn 1 ,

3-b=2

-b=2-3

b=1

Hence the value of a=3 and b=1.
