Answer 1

$1) \frac{ \frac{1}{2} }{ \frac{5}{6}x- \frac{1}{3} } = \frac{1}{8} + \frac{1}{4} \\\\ \frac{5}{6}x- \frac{1}{3} = \frac{ \frac{1}{2} }{ \frac{3}{8} } \\\\ \frac{5}{6}x= \frac{4}{3} + \frac{1}{3} = \frac{5}{3} \\\\ x = \frac{5}{3} : \frac{5}{6} =\frac{5}{3} * \frac{6}{5}=2$

Ответ: 2

$2) \frac{ \frac{2}{3} }{ \frac{2}{9}+ \frac{1}{3} x } = \frac{13}{14} - \frac{1}{2} \\\\ \frac{2}{9}+ \frac{1}{3} x= \frac{ \frac{2}{3} }{ \frac{6}{14} } \\\\ \frac{1}{3} x= \frac{14}{9} - \frac{2}{9} = \frac{12}{9} = \frac{4}{3} \\\\ x= \frac{4}{3} : \frac{1}{3} = \frac{4}{3} *3=4$
