Answer 1

$\begin{cases}\frac15m-\frac16n=0\;\;\times5\\5m-4n=2\end{cases}\Rightarrow\begin{cases}m-\frac56n=0\\5m-4n=2\end{cases}\Rightarrow\begin{cases}m=\frac56n\\5\cdot\frac56n-4n=2\end{cases}\\5\cdot\frac56n-4n=2\\\frac{25}6n-4n=2\\\frac{25-24}6n=2\\\frac16n=2\\n=12\\\begin{cases}m=10\\n=12\end{cases}$
