\[\boxed{\text{344.}\text{\ }\text{Еуроки\ -\ ДЗ\ без\ мороки}}\]
\[\left\{ \begin{matrix} xy = - 8\ \ \ \ \ \ \ \\ 2x + 3y = 6 \\ \end{matrix} \right.\ \text{\ \ \ \ \ \ \ \ }\]
\[\left\{ \begin{matrix} y = - \frac{8}{x}\text{\ \ \ \ \ \ } \\ y = \frac{6 - 2x}{3} \\ \end{matrix} \right.\ \]
\[y = - \frac{8}{x}\]
\[x\] | \[2\] | \[4\] | \[8\] | \[- 2\] | \[- 4\] | \[- 8\] |
---|---|---|---|---|---|---|
\[y\] | \[- 4\] | \[- 2\] | \[- 1\] | \[4\] | \[2\] | \[1\] |
\[y = \frac{6 - 2x}{3}\]
\[x\] | \[0\] | \[3\] |
