\[\boxed{\text{3}\text{83}\text{.}\text{\ }\text{Еуроки\ -\ ДЗ\ без\ мороки}}\]
\[1)\ \left\{ \begin{matrix} x^{3} = y\ \ \ \ \ \ \ \ \ \ \ \\ 2x - 3y = 6 \\ \end{matrix} \right.\ \text{\ \ }\]
\[\left\{ \begin{matrix} y = x^{3}\text{\ \ \ \ \ \ \ \ \ \ \ } \\ 3y = 2x - 6 \\ \end{matrix} \right.\ \]
\[\left\{ \begin{matrix} y = x^{3}\text{\ \ \ \ \ \ \ \ \ } \\ y = \frac{2}{3}x - 2 \\ \end{matrix} \right.\ \]
\[одно\ решение.\]
\[2)\ \left\{ \begin{matrix} y = x^{3} \\ xy = 4 \\ \end{matrix} \right.\ \text{\ \ }\]
\[\left\{ \begin{matrix} y = x^{3} \\ y = \frac{4}{x}\text{\ \ } \\ \end{matrix} \right.\ \]
