Answer 11

Actually, I use calculator to get the answer to make sure it is 100%correct. But if you want to get the method, here it is
the matrix is \[\left[\begin{matrix}1&-3&-1\\-5&16&5\end{matrix}\right]\]
time 5 to row1 + row 2, you get \[\left[\begin{matrix}1&-3&-1\\0&1&0\end{matrix}\right]\]
time3 to row 2 +row 1, you get
\[\left[\begin{matrix}1&0&-1\\0&1&0\end{matrix}\right]\]
that means x = -1, y =0
