\[\left\{ \begin{matrix} 4x - 5y = 2\ \ \ \ \ \ | \cdot 3 \\ 6x - 7y = - 1\ \ \ | \cdot 2 \\ \end{matrix} \right.\ \text{\ \ \ \ \ \ \ }\]
\[\left\{ \begin{matrix} 12x - 15y = 6\ \ \ \\ 12x - 14y = - 2 \\ \end{matrix} - \right.\ \text{\ \ \ \ \ \ }\]
\[\left\{ \begin{matrix} - y = 8\ \ \ \ \ \ \ \\ x = \frac{2 + 5y}{4} \\ \end{matrix} \right.\ \text{\ \ \ \ \ \ \ \ \ \ \ \ }\]
\[\left\{ \begin{matrix} y = - 8\ \ \ \\ x = - 9,5 \\ \end{matrix} \right.\ \]
\[Ответ:( - 9,5;\ - 8)\text{.\ }\]
