\[\boxed{\mathbf{1433}\mathbf{.}}\]
\[\left\{ \begin{matrix} - 3x - 18 < 50x - 180 \\ 5x - 10 > 10 + x\ \ \ \ \ \ \ \ \ \ \ \\ \end{matrix} \right.\ \]
\[\left\{ \begin{matrix} 47x > 162 \\ 4x > 20\ \ \ \ \ \\ \end{matrix} \right.\ \]
\[\left\{ \begin{matrix} x > 3\frac{21}{47} \\ x > 5\ \ \ \ \ \ \\ \end{matrix} \right.\ \]
\(Ответ:\ \ x > 5.\)
