Answer
3+11 does not 13, it equals 14. And the question is terrible anyways. It's more of an English question than a math question, and the wording doesn't make sense. "determined by multiplying by x": multiplying WHAT by x? Even to a native speaker, this question doesn't make sense. You shouldn't need 3 equations to solve for 2 variables, anyways. Bad question all around.

The answer is indeed 14, but you don't need 3 equations to determine it:
Equation 1: 55*x + y = 176 (176 - y)/55 = x
Equation 2: 176*x + y = 539
(176 * (176 - y))/55 + y = 539 30976/55 - (176/55)y + y = 539 563.2 - 539 = 3.2y - y 24.2 = 2.2y y = 11
55*x + 11 = 176 x = 3
x + y = 14

13. The answer is 13.
You can't have this image on Wikipedia and not let us give the answer. The answer is 13.
