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