\[\left\{ \begin{matrix} 5x - 25 < x\ \ \\ 4x + 13 \geq 11 \\ \end{matrix} \right.\ \Longrightarrow \left\{ \begin{matrix} 5x - x < 25\ \ \\ 4x \geq 11 - 13 \\ \end{matrix} \right.\ \]
\[\left\{ \begin{matrix} 4x < 25 \\ 4x \geq - 2 \\ \end{matrix} \right.\ \Longrightarrow \left\{ \begin{matrix} x < 6,25\ \\ x \geq - 0,5 \\ \end{matrix} \right.\ \]
\[Ответ:3)\ \lbrack - 0,5;6,25).\]
