Решите пожалуйста2 3/5:(х+1 3/14)-1 2/5=1/3

$2\frac{3}{5}:(x+1\frac{3}{14})-1\frac{2}{5}=\frac{1}{3}$

$\frac{13}{5}:(x+\frac{17}{14})=\frac{1}{3}+\frac{7}{5}$

$\frac{13}{5}:(x+\frac{17}{14})=\frac{5+21}{15}$

$\frac{13}{5}:(x+\frac{17}{14})=\frac{26}{15}$

$(x+\frac{17}{14})=\frac{13}{5}:\frac{26}{15}$

$(x+\frac{17}{14})=\frac{13}{5}*\frac{15}{26}$

$x+\frac{17}{14}=\frac{3}{2}$

$x=\frac{3}{2}-\frac{17}{14}$

$x=\frac{21-17}{14}$

$x=\frac{4}{14}$

$x=\frac{2}{7}$
