5.Решите уравнения. a) \(3\frac{8}{9} - x = 1\frac{5}{9}\) б) \((y-8\frac{12}{19}) + 1\frac{7}{19} = \frac{7}{19}\)

• а) \(3\frac{8}{9} - x = 1\frac{5}{9}\)

\(x = 3\frac{8}{9} - 1\frac{5}{9}\) \(x = 2\frac{3}{9}\) \(x = 2\frac{1}{3}\)

• б) \((y-8\frac{12}{19}) + 1\frac{7}{19} = \frac{7}{19}\)

\(y-8\frac{12}{19} = \frac{7}{19} - 1\frac{7}{19}\) \(y - 8\frac{12}{19} = -1\) \(y = -1 + 8\frac{12}{19}\) \(y = 7\frac{12}{19}\) Ответ: а) \(x = 2\frac{1}{3}\); б) \(y = 7\frac{12}{19}\)
