You can put this solution on YOUR website!
y x y = 112 =
y%5E2+=+112
to get y by itself, take the square root of both sides:
sqrt%28y%5E2%29+=+sqrt%28112%29
simplify the root by finding what, if any, products of 112 are perfect squares:
16 x 7 = 112, and 16 is a perfect square, so the square root of 112 reduces down to 4sqrt%287%29
FINAL ANSWER: y+=+4sqrt%287%29
