Решите неравенство: 5*(y-1,4)-6<4y-1,5

Ответ:

\[\ 5 \cdot (y - 1,4) - 6 < 4y - 1,5\]

\[5y - 7 - 6 < 4y - 1,5\]

\[y < 11,5.\]

\[\frac{m + 1}{3} < m - 6\]

\[m + 1 < 3m - 18\]

\[- 2m < - 19\]

\[m > 9,5.\]

\[\ \left\{ \begin{matrix} 3x - 9 < 0 \\ 5x + 2 > 0 \\ \end{matrix} \right.\ \text{\ \ \ \ \ }\left\{ \begin{matrix} 3x < 9\ \ \ \\ 5x > - 2 \\ \end{matrix} \right.\ \text{\ \ \ \ \ }\left\{ \begin{matrix} x < 3\ \ \ \ \ \ \\ x > - 0,4 \\ \end{matrix} \right.\ \]

\[Ответ:\ x \in ( - 0,4;\ 3)\text{.\ }\]
