Here's the Solution to this Question

Given, the ordered pairs (x + y, x - y) and (2x + 3y, 3x - 2y) are equal. Since, two ordered pairs are equal if and only if corresponding coordinates are equal, we get x+y=2x+3y and x-y=3x-2y . That is -x-2y = 0 and -2x + y = 0. Solving the two equations, we get x = 0 and y = 0 . Hence the ordered pair (x,y) = (0,0).
