\[\left\{ \begin{matrix} 3x + 2y = 7 \\ x - 2y = - 3 \\ \end{matrix} \right.\ \text{\ \ \ \ \ }\]
\[\left\{ \begin{matrix} x = 2y - 3\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \\ 3 \cdot (2y - 3) + 2y = 7 \\ \end{matrix} \right.\ \text{\ \ \ \ \ }\]
\[\left\{ \begin{matrix} x = 2y - 3\ \ \ \ \ \ \ \ \ \ \\ 6y - 9 + 2y = 7 \\ \end{matrix} \right.\ \]
\[\left\{ \begin{matrix} x = 2y - 3 \\ 8y = 16\ \ \ \ \ \\ \end{matrix} \right.\ \text{\ \ \ \ \ \ }\]
\[\left\{ \begin{matrix} y = 2\ \ \ \ \ \ \ \ \ \ \ \ \ \ \\ x = 2 \cdot 2 - 3 \\ \end{matrix} \right.\ \text{\ \ \ \ \ \ \ }\]
\[\left\{ \begin{matrix} y = 2 \\ x = 1 \\ \end{matrix} \right.\ \]
\[Проверка:\ \]
\[\left\{ \begin{matrix} 3 \cdot 1 + 2 \cdot 2 = 7 \\ 1 - 2 \cdot 2 = - 3\ \ \\ \end{matrix} \right.\ \text{\ \ \ \ \ }\]
\[\left\{ \begin{matrix} 7 = 7\ \ \ \ \ \ \ \\ - 3 = - 3 \\ \end{matrix} \right.\ \Longrightarrow верно.\]
