Accepted Answer

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

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

\[y = x + 5\]

\[x\]	\[0\]	\[- 1\]
\[y\]	\[5\]	\[4\]

\[y = 2 - 0,5x\]

\[x\]	\[0\]	\[2\]
\[y\]	\[2\]	\[1\]

\[Ответ:( - 2;3).\]
