\[\frac{4}{x} = - |x|\]
\[\left\{ \begin{matrix} y = \frac{4}{x}\text{\ \ \ \ \ \ \ } \\ y = - |x| \\ \end{matrix} \right.\ \]
\[y = \frac{4}{x}\]
| \[x\] | \[1\] | \[2\] | \[4\] | \[- 1\] | \[- 2\] | \[- 4\] |
|---|---|---|---|---|---|---|
| \[y\] | \[4\] | \[2\] | \[1\] | \[- 4\] | \[- 2\] | \[- 1\] |
\[y = - |x|\]
| \[x\] | \[0\] | \[1\] | \[- 1\] |
|---|---|---|---|
| \[y\] | \[0\] | \[- 1\] | \[- 1\] |

\[Ответ:x = - 2.\]
