Решите систему уравнений: 4x-5y=12, 6x+11y=-19.

\[\left\{ \begin{matrix} 4x - 5y = 12\ \ \ \ \ \ \ \ \ | \cdot 3 \\ 6x + 11y = - 19\ \ \ | \cdot 2 \\ \end{matrix} \right.\ \text{\ \ \ \ \ \ \ }\]

\[\left\{ \begin{matrix} 12x - 15y = 36\ \ \ \\ 12x + 22y = - 38 \\ \end{matrix} - \right.\ \text{\ \ \ \ \ }\]

\[\left\{ \begin{matrix} - 37y = 74\ \ \\ x = \frac{12 + 5y}{4} \\ \end{matrix} \right.\ \text{\ \ \ \ \ \ \ \ \ \ \ \ }\]

\[\left\{ \begin{matrix} y = - 2 \\ x = 0,5 \\ \end{matrix} \right.\ \]

\[Ответ:(0,5;\ - 2).\]
