Accepted Answer

\[\frac{4}{x} = - |x|\]

\[\left\{ \begin{matrix} y = \frac{4}{x}\text{\ \ \ \ \ \ \ } \\ y = - |x| \\ \end{matrix} \right.\ \]

\[y = \frac{4}{x}\]

\[x\]	\[1\]	\[2\]	\[4\]	\[- 1\]	\[- 2\]	\[- 4\]
\[y\]	\[4\]	\[2\]	\[1\]	\[- 4\]	\[- 2\]	\[- 1\]

\[y = - |x|\]

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

\[Ответ:x = - 2.\]
