Q.7. If x=a and y=b is the
solution of the pair of
equations x- y = 2 and x + y= 4,
then the respective values of a
and b are​

Answer 1

Answer:Given, x−y=2 and x+y=4.

Adding both the equations, we get 2x=6

⇒x=3

Putting the value of x in one of the equations, we get

3−y=2 ⇒y=1

As stated in the question, x=a and y=b.

Thus, a=3 and b=1
