2.Решите уравнение: а) $$\frac{17}{71}+x=\frac{41}{71}$$; б) $$\frac{28}{35}-y=\frac{13}{35}$$

а) $$\frac{17}{71}+x=\frac{41}{71}$$

$$x=\frac{41}{71}-\frac{17}{71}$$

$$x=\frac{41-17}{71}$$

$$x=\frac{24}{71}$$

б) $$\frac{28}{35}-y=\frac{13}{35}$$

$$y=\frac{28}{35}-\frac{13}{35}$$

$$y=\frac{28-13}{35}$$

$$y=\frac{15}{35}$$

$$y=\frac{3}{7}$$

Ответ: а) $$\frac{24}{71}$$; б) $$\frac{3}{7}$$
