Решим уравнения:

А) $$x + 3 \frac{2}{5} = 5 \frac{3}{5}$$

$$x = 5 \frac{3}{5} - 3 \frac{2}{5}$$

$$x = 2 \frac{1}{5}$$

Ответ: $$x = 2 \frac{1}{5}$$

Б) $$x + 3 \frac{1}{5} = 5 \frac{2}{5}$$

$$x = 5 \frac{2}{5} - 3 \frac{1}{5}$$

$$x = 2 \frac{1}{5}$$

Ответ: $$x = 2 \frac{1}{5}$$

В) $$x + 13 \frac{1}{19} = 47 \frac{4}{19}$$

$$x = 47 \frac{4}{19} - 13 \frac{1}{19}$$

$$x = 34 \frac{3}{19}$$

Ответ: $$x = 34 \frac{3}{19}$$

Г) $$4 \frac{3}{8} + x = 9 \frac{1}{12}$$

$$x = 9 \frac{1}{12} - 4 \frac{3}{8}$$

$$x = 9 \frac{2}{24} - 4 \frac{9}{24}$$

$$x = 8 \frac{26}{24} - 4 \frac{9}{24}$$

$$x = 4 \frac{17}{24}$$

Ответ: $$x = 4 \frac{17}{24}$$

Д) $$4 \frac{1}{17} + x = \frac{5}{68}$$

$$x = \frac{5}{68} - 4 \frac{1}{17}$$

$$x = \frac{5}{68} - \frac{69}{17}$$

$$x = \frac{5}{68} - \frac{276}{68}$$

$$x = -\frac{271}{68} = -3 \frac{67}{68}$$

Ответ: $$x = -3 \frac{67}{68}$$

Е) $$x - 6 \frac{2}{3} = 7 \frac{11}{15}$$

$$x = 7 \frac{11}{15} + 6 \frac{2}{3}$$

$$x = 7 \frac{11}{15} + 6 \frac{10}{15}$$

$$x = 13 \frac{21}{15}$$

$$x = 14 \frac{6}{15} = 14 \frac{2}{5}$$

Ответ: $$x = 14 \frac{2}{5}$$

Ё) $$x - 9 \frac{11}{12} = 7 \frac{5}{24}$$

$$x = 7 \frac{5}{24} + 9 \frac{11}{12}$$

$$x = 7 \frac{5}{24} + 9 \frac{22}{24}$$

$$x = 16 \frac{27}{24} = 17 \frac{3}{24} = 17 \frac{1}{8}$$

Ответ: $$x = 17 \frac{1}{8}$$

Ж) $$4 \frac{5}{6} - x = 2 \frac{1}{3}$$

$$x = 4 \frac{5}{6} - 2 \frac{1}{3}$$

$$x = 4 \frac{5}{6} - 2 \frac{2}{6}$$

$$x = 2 \frac{3}{6} = 2 \frac{1}{2}$$

Ответ: $$x = 2 \frac{1}{2}$$

З) $$8 \frac{7}{8} - x = 5 \frac{1}{4}$$

$$x = 8 \frac{7}{8} - 5 \frac{1}{4}$$

$$x = 8 \frac{7}{8} - 5 \frac{2}{8}$$

$$x = 3 \frac{5}{8}$$

Ответ: $$x = 3 \frac{5}{8}$$
