\[\left\{ \begin{matrix} y = - x + 1\ \ \ \ \ \ \ \ \ \ \ \ \\ x^{2} + (y + 3)^{2} = 8 \\ \end{matrix}\text{\ \ \ \ \ \ } \right.\ \text{\ \ \ \ \ \ \ \ \ \ \ \ }\]
\[\left\{ \begin{matrix} y = - x + 1\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \\ x^{2} + ( - x + 1 + 3)^{2} = 8 \\ \end{matrix}\text{\ \ \ \ \ } \right.\ \]
\[\left\{ \begin{matrix} y = - x + 1\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \\ x^{2} + 16 - 8x + x^{2} - 8 = 0 \\ \end{matrix} \right.\ \]
\[2x^{2} - 8x + 8 = 0\ \ \ \ \ \ |\ :2\]
\[x^{2} - 4x + 4 = 0\]
\[(x - 2)^{2} = 0\]
\[x = 2\]
\[\left\{ \begin{matrix} x = 2\ \ \ \\ y = - 1 \\ \end{matrix} \right.\ \]
\[Ответ:(2;\ - 1).\]
