Answer:


x=-1


y=5

Explanation:


\begin{pmatrix}x&y\\ \:-1&4\end{pmatrix}\begin{pmatrix}2&5\\ \:4&1\end{pmatrix}=\begin{pmatrix}18&0\\ \:14&-1\end{pmatrix}


\begin{pmatrix}x&y\\ -1&4\end{pmatrix}\begin{pmatrix}2&5\\ 4&1\end{pmatrix}


=\begin{pmatrix}x* \:2+y* \:4&5x+y\\ 14&-1\end{pmatrix}


=\begin{pmatrix}18&0\\ 14&-1\end{pmatrix}


\begin{bmatrix}x* \:2+y* \:4=18\\ 5x+y=0\end{bmatrix}


x=-1


y=5
