Решите уравнения: г) -8/9 - (n - 1) = 7/18; д) 1 5/9 - (s + 4/9) = 2/3; е) -5 4/7 + (-5/14 + z) = 3 1/7

г) $-\frac{8}{9} - (n - 1) = \frac{7}{18}$ $-(n - 1) = \frac{7}{18} + \frac{8}{9}$ $-(n - 1) = \frac{7}{18} + \frac{16}{18}$ $-(n - 1) = \frac{23}{18}$ $n - 1 = -\frac{23}{18}$ $n = 1 - \frac{23}{18}$ $n = \frac{18}{18} - \frac{23}{18}$ $n = -\frac{5}{18}$ **Ответ: $-5/18$** д) $1\frac{5}{9} - (s + \frac{4}{9}) = \frac{2}{3}$ $-(s + \frac{4}{9}) = \frac{2}{3} - 1\frac{5}{9}$ $-(s + \frac{4}{9}) = \frac{6}{9} - \frac{14}{9}$ $-(s + \frac{4}{9}) = -\frac{8}{9}$ $s + \frac{4}{9} = \frac{8}{9}$ $s = \frac{8}{9} - \frac{4}{9}$ $s = \frac{4}{9}$ **Ответ: $4/9$** е) $-5\frac{4}{7} + (-\frac{5}{14} + z) = 3\frac{1}{7}$ $-\frac{5}{14} + z = 3\frac{1}{7} + 5\frac{4}{7}$ $-\frac{5}{14} + z = 8\frac{5}{7}$ $z = 8\frac{5}{7} + \frac{5}{14}$ $z = 8\frac{10}{14} + \frac{5}{14}$ $z = 8\frac{15}{14} = 9\frac{1}{14}$ **Ответ: $9\frac{1}{14}$**
