\[\boxed{\text{69\ (69).}\text{\ }\text{Еуроки\ -\ ДЗ\ без\ мороки}}\]
\[1)\ 2x - |x| = - 1\]
\[x \geq 0;\ \ |x| = x:\]
\[2x - x = - 1\]
\[x = - 1\ (не\ удовлетворяет).\]
\[x < 0;\ \ \ |x| = - x:\]
\[2x + x = 1\]
\[3x = - 1\]
\[x = - \frac{1}{3}.\]
\[Ответ:\ x = - \frac{1}{3}.\]
\[2)\ 7 \cdot |x| - 3 \cdot (x + 2) = - 10\]
\[x \geq 0;\ \ |x| = x:\]
\[7x - 3x - 6 = - 10\]
\[4x = - 10 + 6\]
\[4x = - 4\]
\[x = - 1\ (не\ удовлетворяет).\]
\[x < 0;\ \ |x| = - x:\]
\[- 7x - 3x - 6 = - 10\]
\[- 10x = - 10 + 6\]
\[- 10x = - 4\]
\[x = 0,4\ (не\ удовлетворяет)\]
\[Ответ:нет\ корней.\]
