Ответ:
\[\left\{ \begin{matrix} x = - 1\ \ \ \ \ \ \ \\ 2x + y = 3 \\ \end{matrix} \right.\ \text{\ \ \ \ \ \ \ \ \ }\]
\[\left\{ \begin{matrix} x = - 1\ \ \ \ \ \ \ \ \\ y = 3 - 2x \\ \end{matrix} \right.\ \]
\[x = - 1\]
\[y = 3 - 2x\]
| \[x\] | \[0\] | \[1\] |
|---|---|---|
| \[y\] | \[3\] | \[1\] |

\[Ответ:( - 1;5).\]
