\[\left\{ \begin{matrix} 3x - 2y = 16\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \\ x + 4y = - 4\ \ \ | \cdot ( - 3) \\ \end{matrix} \right.\ \text{\ \ \ \ \ \ \ \ \ \ }\]
\[\left\{ \begin{matrix} 3x - 2y = 16\ \ \ \ \ \ \ \ \ \ (1) \\ - 3x - 12y = 12\ \ \ \ (2) \\ \end{matrix} \right.\ \]
\[(1) + (2) \Longrightarrow - 14y = 28,\ \ y = - 2.\]
\[\left\{ \begin{matrix} y = - 2\ \ \ \ \ \ \ \ \ \ \\ x = - 4 - 4y \\ \end{matrix} \right.\ \text{\ \ \ \ \ \ \ \ \ \ }\left\{ \begin{matrix} y = - 2\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \\ x = - 4 - 4 \cdot ( - 2) \\ \end{matrix} \right.\ \text{\ \ \ \ \ \ \ \ \ \ }\]
\[\left\{ \begin{matrix} y = - 2\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \\ x = - 4 + 8 = 4 \\ \end{matrix} \right.\ \]
\[Ответ:(4;\ - 2).\]
