Решите номер 559(1 и 2 пример)

$\frac{ \frac{2}{5} }{ \frac{3}{5}x- \frac{1}{5} }= \frac{1}{20} + \frac{1}{5} \\ \frac{ \frac{2}{5} }{ \frac{3}{5}x- \frac{1}{5} }= \frac{1}{4} \\ \frac{1}{4} *( \frac{3}{5} x- \frac{1}{5} )= \frac{2}{5} \\ \frac{3}{20} x- \frac{1}{20} = \frac{2}{5} \\ \frac{3}{20} x= \frac{2}{5} + \frac{1}{20} \\ \frac{3}{20} x= \frac{9}{20} \\ x= \frac{9}{20} * \frac{20}{3} \\ x=3 \\ =$

$\frac{ \frac{2}{3} }{ \frac{5}{6}x- \frac{1}{6} }= \frac{7}{9} - \frac{1}{3} \\ \frac{ \frac{2}{3} }{ \frac{5}{6}x- \frac{1}{6} }= \frac{4}{9} \\ \frac{4}{9} *( \frac{5}{6} x- \frac{1}{6} )= \frac{2}{3} \\ \frac{10}{27} x- \frac{2}{27} = \frac{2}{3} \\ \frac{10}{27} x= \frac{2}{3} + \frac{2}{27} \\ \frac{10}{27}x= \frac{20}{27} \\ x= \frac{20}{27} * \frac{27}{10} \\ x=2 \\ \$
