Решение уравнений

 $5\ \frac{11}{14}\ X\ -\ \frac{8}{15}=\frac{5}{21}$  

 $7\ \frac{3}{10}\ \ +\ \frac{25}{28}\ X=8\frac{13}{35}$  

 $3\ \frac{1}{3}\ \ -\ 1\frac{1}{20}X=1\frac{14}{15}$  

 $\frac{3}{8}\ X\ +\ \frac{7}{12}X-\frac{5}{6}X=\frac{9}{32}$  

 $2\ \frac{1}{3}\div X\ \ -\ 1\frac{1}{6}=1\frac{5}{9}$  

 $2\ \frac{1}{3}\div\left(X\ \ -\ 1\frac{1}{6}\right)=1\frac{5}{9}$  

 $2\ 7\div\left(30\ \frac{3}{7}\ \ -\ 2\frac{11}{14}X\right)=1\frac{1}{8}$  

 $48\div\left(3\ \frac{4}{5}X\ \ -\ 25\right)=1\frac{1}{2}$
