Question

3. If x = a, y = b is the solution of the pair of equations x - y = 2 and x + y = 4, then find the
values of a and b.​

Answer 1

Answer:

:. we can know that x-y=2 but also we know that x+y=4 the we can say that x and y are 2

so then we get into the question they ask that is x=a and y=b then x=2 so, x=a that means a=2

and next y=b and this is also 2 only because y=2 then y=b means b=2 only
