\[\boxed{\text{338\ (338).}\text{\ }\text{Еуроки\ -\ ДЗ\ без\ мороки}}\]
\[y = - x:\]
\[- x = - \frac{25}{x}\]
\[\frac{25}{x} - x^{\backslash x} = 0\]
\[\frac{25 - x^{2}}{x} = 0\]
\[\left\{ \begin{matrix} 25 - x^{2} = 0 \\ x \neq 0\ \ \ \ \ \ \ \ \ \ \ \\ \end{matrix} \right.\ \text{\ \ \ \ \ \ }\left\{ \begin{matrix} x = 5\ \ \ \\ x = - 5 \\ x \neq 0\ \ \ \\ \end{matrix} \right.\ \]
