\[\left\{ \begin{matrix} 2x - 7 > 6\ \\ 3 - 4x < 9 \\ 7x - 8 > 2 \\ \end{matrix}\text{\ \ \ \ \ \ \ \ } \right.\ \]
\[\left\{ \begin{matrix} 2x > 13 \\ 4x > - 6 \\ 7x > 10 \\ \end{matrix}\text{\ \ \ \ } \right.\ \text{\ \ \ \ }\]
\[\left\{ \begin{matrix} x > 6,5 \\ x > - \frac{6}{4} \\ x > \frac{10}{7} \\ \end{matrix} \right.\ \]
\[Ответ:(6,5;\ + \infty).\]
