Accepted Answer

\[\left\{ \begin{matrix} x = - 1\ \ \ \ \ \ \ \\ 2x + y = 3 \\ \end{matrix} \right.\ \text{\ \ \ \ \ \ \ \ \ }\]

\[\left\{ \begin{matrix} x = - 1\ \ \ \ \ \ \ \ \\ y = 3 - 2x \\ \end{matrix} \right.\ \]

\[x = - 1\]

\[y = 3 - 2x\]

\[x\]	\[0\]	\[1\]
\[y\]	\[3\]	\[1\]

\[Ответ:( - 1;5).\]
