Решение:
- $$x+4\frac{4}{19}=6\frac{2}{19}$$
$$x = 6\frac{2}{19} - 4\frac{4}{19}$$
$$x = (6-4) + (\frac{2}{19} - \frac{4}{19})$$
$$x = 2 - \frac{2}{19}$$
$$x = 1\frac{19}{19} - \frac{2}{19} = 1\frac{17}{19}$$
- $$25-x=8\frac{3}{14}$$
$$x=25-8\frac{3}{14}$$
$$x = 25-8 - \frac{3}{14} = 17 - \frac{3}{14} = 16\frac{14}{14} - \frac{3}{14} = 16\frac{11}{14}$$
Ответ: 1) $$1\frac{17}{19}$$; 2) $$16\frac{11}{14}$$.
