Решите уравнения |2x-6|=1 и ||x|-7 1/3|=4.5

Решите задачу:

$1)\; |2x-6|=1\\\\2x-6=1\; \; \; ili\; \; \; 2x-6=-1\\\\x=3,5\; \; \; ili\; \; \; x=2,5\\\\2)\; ||x|-7\frac{1}{3}|=4,5\\\\a)\; |x|-\frac{22}{3}=\frac{9}{2},\; \; |x|=\frac{9}{2}+\frac{22}{3}=\frac{71}{6}\\\\x=\frac{71}{6}\; \; ili\; \; x=-\frac{71}{6}\\\\b)\; |x|-\frac{22}{3}=-\frac{9}{2},\; |x|=-\frac{9}{2}+\frac{22}{3}=\frac{17}{6}\\\\x=\frac{17}{6}\; \; ili\; \; x=-\frac{17}{6}\\\\Otvet:\; x=\pm \frac{71}{6},\; x=\pm \frac{17}{6}$
