\[\left\{ \begin{matrix} 4m - 5n = 1\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \\ 2m - 3n = 2\ \ \ | \cdot ( - 2) \\ \end{matrix} \right.\ \text{\ \ \ \ }\]
\[\left\{ \begin{matrix} 4m - 5n = 1\ \ \ \ \ \ \ \ \ \ (1) \\ - 4m + 6n = - 4\ \ \ (2) \\ \end{matrix} \right.\ \]
\[(1) + (2) \Longrightarrow n = - 3\]
\[\left\{ \begin{matrix} n = - 3\ \ \ \ \ \ \ \ \ \ \ \ \\ 2m - 3n = 2 \\ \end{matrix} \right.\ \text{\ \ \ \ \ \ }\]
\[\left\{ \begin{matrix} n = - 3\ \ \ \ \ \ \ \ \ \ \ \\ 2m = 2 + 3n \\ \end{matrix} \right.\ \text{\ \ \ \ \ }\]
\[\left\{ \begin{matrix} n = - 3\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \\ m = 1 + \frac{3}{2} \cdot ( - 3) \\ \end{matrix} \right.\ \text{\ \ \ }\]
\[\left\{ \begin{matrix} n = - 3\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \\ m = - \frac{7}{2} = - 3,5 \\ \end{matrix} \right.\ \]
\[Ответ:( - 3,5;\ - 3).\]
