Решебник по алгебре 7 класс Мерзляк ФГОС Задание 1026

\[\boxed{\text{1026\ (1026).}\text{\ }\text{Еуроки\ -\ ДЗ\ без\ мороки}}\]

\[x = 3 - 2y\]

\(\ \)

\[Ответ:(1;1),\ ( - 3;3).\]

\[y = 3 + 2x\]

\[y = 2x - 3\]

\[x = 2y\]

\(\ \)

\[Ответ:( - 2;\ - 1),(2;1).\]

\[\left\{ \begin{matrix} x - y = 2 \\ x - y = - 2 \\ x + y = 2 \\ x + y = - 2 \\ \end{matrix} \right.\ \text{\ \ \ \ \ \ \ }\left\{ \begin{matrix} y = x - 2 \\ y = x + 2 \\ y = 2 - x \\ y = - 2 - x \\ \end{matrix} \right.\ \]

\[y = x - 2\]

\[y = x + 2\]

\[y = 2 - x\]

\[y = - 2 - x\]

\(\ \)

\[Ответ:( - 2;0),\ (0;\ - 2),\ (0;2),\ \]

\[(2;0)\text{.\ }\]

\[\boxed{\text{1026.\ }\text{Еуроки\ -\ ДЗ\ без\ мороки}}\]

\[1)\]

\[2)\ y( - 2) = 4\]

\[y(0) = 1\]

\[y(2) = - 1\]

\[y(6) = - 1\]

\[3)\ y = 1 \Longrightarrow \text{\ \ }x = 0\]

\[y = - 1 \Longrightarrow \text{\ \ }x = - 2;\ \ x = 6\]

\[y = 0 \Longrightarrow \ \ x = 1;\ \ x = 9\]
