\[\left\{ \begin{matrix} 3x - 5y = 14\ \ \ | \cdot 2 \\ 2x - 7y = 2\ \ \ \ \ | \cdot 3 \\ \end{matrix} \right.\ \text{\ \ \ \ \ \ }\]
\[\left\{ \begin{matrix} 6x - 10y = 28 \\ 6x - 21y = 6\ \ \\ \end{matrix} \right.\ - \ \ \ \ \]
\[\left\{ \begin{matrix} 11y = 22\ \ \ \ \ \ \ \ \\ x = \frac{28 + 10y}{6} \\ \end{matrix} \right.\ \text{\ \ \ \ \ \ \ \ \ \ \ \ \ \ }\]
\[\left\{ \begin{matrix} y = 2 \\ x = 8 \\ \end{matrix} \right.\ \]
\[Ответ:(8;2).\]
