Решение:
$$\frac{5}{6}$$ х -  $$\frac{5}{6}$$ =  $$\frac{9}{4}$$ -  $$\frac{11}{8}$$
$$\frac{5}{6}$$ х -  $$\frac{5}{6}$$ =  $$\frac{18}{8}$$ -  $$\frac{11}{8}$$
$$\frac{5}{6}$$ х -  $$\frac{5}{6}$$ =  $$\frac{7}{8}$$
$$\frac{5}{6}$$ х =  $$\frac{7}{8}$$ +  $$\frac{5}{6}$$
$$\frac{5}{6}$$ х =  $$\frac{21}{24}$$ +  $$\frac{20}{24}$$
$$\frac{5}{6}$$ х =  $$\frac{41}{24}$$
х =  $$\frac{41}{24}$$ :  $$\frac{5}{6}$$
х =  $$\frac{41}{24}$$ *  $$\frac{6}{5}$$
х =  $$\frac{41}{20}$$
х = 2  $$\frac{1}{20}$$
