3. Решите уравнение: a) x-3,22=-8,19; б) \(\frac{2}{15}+y=-1\frac{10}{7}\)

a) \(x - 3,22 = -8,19\) \(x = -8,19 + 3,22\) \(x = -4,97\) б) \(\frac{2}{15} + y = -1 \frac{10}{7}\) \(y = -1 \frac{10}{7} - \frac{2}{15}\) \(y = -\frac{17}{7} - \frac{2}{15}\) \(y = -\frac{255}{105} - \frac{14}{105}\) \(y = -\frac{269}{105} = -2 \frac{59}{105}\)
