Реши уравнение: y+4 7/10=5 8/15.

\[y + 4\frac{7}{10} = 5\frac{8}{15}\]

\[y = 5\frac{8^{\backslash 2}}{15} - 4\frac{7^{\backslash 3}}{10}\]

\[y = 5\frac{16}{30} - 4\frac{21}{30}\]

\[y = 4\frac{46}{30} - 4\frac{21}{30}\]

\[y = \frac{46 - 21}{30} = \frac{25}{30}\]

\[y = \frac{5}{6}\ \]

\[Ответ:y = \frac{5}{6}\text{.\ }\]
