Решите уравнения: 1) 1/2 y - 1/3 = 5/18 - 8/9 y 2) x/1,6 = 1,35/ 0,36

Решите задачу:

$\frac{1}{2}y - \frac{1}{3} = \frac{5}{18} - \frac{8}{9}y \\ \frac{1}{2}y + \frac{8}{9}y = \frac{5}{18} + \frac{1}{3} \\ \frac{9}{18}y + \frac{16}{18}y = \frac{5}{18} + \frac{6}{18} \\ \frac{25}{18}y = \frac{11}{18} |*18 \\ 25y = 11 \\ y = \frac{11}{25} \\ y= 0.44$

$\\ \frac{x}{1,6} = \frac{1,35}{0,36} \\ 0.36x = 1.35 * 1.6 \\ 0.36x = 2.16 \\ x = 2.16 : 0.36 \\ x = 6$
