Решите систему уравнений 4x+y=-10, 5x-2y=-19.

\[\left\{ \begin{matrix} 4x + y = - 10\ \ \ \ \ \ | \cdot 2 \\ 5x - 2y = - 19\ \ \ \ \ \ \ \ \ \ \ \\ \end{matrix} \right.\ \]

\[\left\{ \begin{matrix} 8x + 2y = - 20 \\ 5x - 2y = - 19 \\ \end{matrix}( + ) \right.\ \]

\[\left\{ \begin{matrix} 13x = - 39\ \ \ \ \\ y = - 10 - 4x \\ \end{matrix} \right.\ \Longrightarrow \left\{ \begin{matrix} x = - 3 \\ y = 2\ \ \ \\ \end{matrix} \right.\ \]

\[Ответ:( - 3;2)\text{.\ }\]
