  1. Unless you'd like to solve the problem using substitution, which is not hard to do, you could substitute the given answers into the given equations.

    From the second equation, x+y=2, we can eliminate the first and the second answer, since the proposed values of x and y add up to more than 2.
    Between the answers 3 and 4, it is obvious that the fourth choice does not satisfy the first equation. So the answer is #3.
