The coefficient of the first equation X is 2, the coefficient of Y is 1, and the result of addition is11; The coefficient of the second equation X is 4, the coefficient of Y is 3, and the result of addition is 27, so the listed equation is 2x+y = 1 14x+3y = 27.

So the answer is 2x+y = 1 14x+3y = 27.
