\[\boxed{\text{206\ (206).}\text{\ }\text{Еуроки\ -\ ДЗ\ без\ мороки}}\]
\[1)\ |x - 6| \geq 2,4\]
\[x - 6 \geq 2,4\ \ \ \ или\ \ \ x - 6 \leq - 2,4\]
\[\ \ \ \ \ \ \ \ x \geq 8,4\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ x \leq 3,6\]
\[Ответ:x \in ( - \infty;3,6\rbrack \cup \lbrack 8,4;\ + \infty).\]
\[2)\ |5x + 8| \leq 2\]
\[- 2 \leq 5x + 8 \leq 2\]
\[- 10 \leq 5x \leq - 6\]
\[- 2 \leq x \leq - \frac{6}{5}\]
\[- 2 \leq x \leq - 1,2\]
\[Ответ:x \in \lbrack - 2;\ - 1,2\rbrack.\]
\[3)\ |x + 5| - 3x > 4\]
\[|x + 5| > 4 + 3x\]
\[Ответ:x \in ( - \infty;0,5).\]
\[4)\ |x - 1| + x \leq 3\]
\[|x - 1| \leq 3 - x\]
\[Ответ:x \in ( - \infty;2\rbrack\text{.\ \ }\]
