\[1)\ |x| - 8 = - 5\]
\[|x| = - 5 + 8\]
\[|x| = 3\]
\[x = \pm 3\]
\[Ответ:x = \pm 3\]
\[2)\ |x| + 5 = 2\]
\[|x| = 2 - 5\]
\[|x| = - 3\]
\[нет\ корней\]
\[Ответ:нет\ корней.\]
\[3)\ |x + 12| = 3\]
\[Ответ:\ x = - 9; - 15\]
\[4)\ |8 - 0,2x| = 12\]
\[Ответ:\ x = - 20;100\]
\[5)\ |10x - 7| - 32 = - 16\]
\[|10x - 7| = - 16 + 32\]
\[|10x - 7| = 16\]
\[Ответ:\ x = 2,3;\ - 0,9.\]
\[6)\ \left| |x| - 2 \right| = 2\]
\[|x| = 4\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ |x| = 0\]
\[x = \pm 4\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ x = 0\]
\[Ответ:x = \pm 4;0.\]
