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

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

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

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

\[Ответ:( - 3;2)\text{.\ }\]
