Notice that both terms in the sum must be >= 0, so to sum to 0 they must both be 0 |x| = 0 only when x = 0 and (anything)^2 = 0 only when the term is 0 so y - 1 =0 or y = 1.

Both of these must happen at the same time so the only solution is x = 0 and y = 1.

The label Linear Algebra is incorrect. This is definitely NOT a Linear Algebra problem.
