rre a, y bis the solution of the pair of equations x-y-2 and x + yvalues of a and b4, find the

Answer»

Given : x = a and y = b is solution of x - y = 2 and x + y = 4.

We have

x - y = 2 ....(1)x + y = 4 ....(2)

Eliminating y by (1) and (2)

2x = 6

x = 3

y = 4 - 3 = 1

So, x = a = 3 and y = b = 1
