\[x\left( - 1 - \frac{4}{x} \right) - 4 = 3 \bullet \left( - 2 - \frac{4}{x} \right)\]
\[- 2x - 4 - 4 = - 6 - \frac{12}{x}\]
\[\frac{12}{x} - 2x = 2\ \ \ \ \ \ \ \ \ | \cdot x\]
\[12 - 2x^{2} = 2x\]
\[2x^{2} + 2x - 12 = 0\ \ \ \ \ |\ :2\]
\[x^{2} + x - 6 = 0\]
\[D = 1^{2} - 4 \cdot 1 \cdot ( - 6) = 1 + 24 =\]
\[= 25\]
\[x_{1} = \frac{- 1 + \sqrt{25}}{2} = \frac{- 1 + 5}{2} = \frac{4}{2} =\]
\[= 2\]
\[x_{2} = \frac{- 1 - \sqrt{25}}{2} = \frac{- 1 - 5}{2} =\]
\[= \frac{- 6}{2} = - 3\]
\[x_{1} = 2 \Longrightarrow \text{\ \ \ \ \ \ \ \ \ }y_{1} = - 2 - \frac{4}{2} =\]
\[= - 2 - 2 = - 4.\]
\[x_{2} = - 3 \Longrightarrow \text{\ \ \ \ \ }y_{2} = - 2 - \frac{4}{- 3} =\]
\[= - 2 + 1\frac{1}{3} = - \frac{2}{3}.\]
\[Ответ:\ \ (2;\ - 4),\ \ \ \left( - 3;\ - \frac{2}{3} \right).\]
