2.468 Найдите корень уравнения: в) n +n = ;

в) $$n + \frac{5}{14}n = \frac{1}{7}$$

$$\frac{14}{14}n + \frac{5}{14}n = \frac{1}{7}$$

$$\frac{19}{14}n = \frac{1}{7}$$

$$n = \frac{1}{7} : \frac{19}{14}$$

$$n = \frac{1}{7} \cdot \frac{14}{19}$$

$$n = \frac{1 \cdot 14}{7 \cdot 19}$$

$$n = \frac{1 \cdot 2}{1 \cdot 19}$$

$$n = \frac{2}{19}$$

Ответ: $$\frac{2}{19}$$
