In the following question, two equations numbered I and II are given. Solve both equations and give the answer: I. y^2 = 49 II. (x - y)^2 = 0

1. x > y
2. x B5 y
3. x = y or the relation cannot be determined
4. x < y

Correct answer: x = y or the relation cannot be determined

Solution

From II, A0(x-y)^2=0 A0implies A0x=y. Equation I gives A0y=B17, but that does not change the relation between x and y. Therefore, the correct relation is x = y.
