Question

A = {(x,y)}/x + y - 7 =0), B = [(x,y)]/x - y + 3 = 0) then find AnB.​

Answer 1

Answer:

(2,5)

Step-by-step explanation:

A n B refers to those relations which are common.

So, for some relations, both exist, and for common x and y. We can say,

x + y - 7 = 0 & x - y + 3 = 0

Add both, x = 2 and y = 5. Thus (x, y) = (2,5).

Hence,

A n B = {(x, y) belonging to both A and B}

A n B = {(2, 5)}
