г) y - \frac{1}{9}y = 5\frac{1}{3};

г) Решим уравнение:

$$y - \frac{1}{9}y = 5\frac{1}{3}$$

$$\frac{9}{9}y - \frac{1}{9}y = \frac{16}{3}$$

$$\frac{8}{9}y = \frac{16}{3}$$

$$y = \frac{16}{3} : \frac{8}{9}$$

$$y = \frac{16}{3} \cdot \frac{9}{8}$$

$$y = \frac{2}{1} \cdot \frac{3}{1}$$

$$y = 6$$
