Решите систему уравнений 3x-y=17, 2x+3y=-7.

\[\left\{ \begin{matrix} 3x - y = 17\ \ \ | \cdot 3 \\ 2x + 3y = - 7\ \ \ \ \ \ \ \\ \end{matrix} \right.\ \]

\[\left\{ \begin{matrix} 9x - 3y = 5\ \ \ \\ 2x + 3y = - 7 \\ \end{matrix}( + \right.\ )\]

\[\left\{ \begin{matrix} 11x = 44\ \ \ \ \ \ \\ y = \frac{- 7 - 2x}{3} \\ \end{matrix} \right.\ \Longrightarrow \left\{ \begin{matrix} x = 4\ \ \ \\ y = - 5 \\ \end{matrix} \right.\ \]

\[Ответ:(4;\ - 5)\text{.\ }\]
