Реши уравнение: y+3 3/14=-1 4/21.

Ответ:

\[y + 3\frac{3}{14} = - 1\frac{4}{21}\]

\[y + \frac{45}{14} = - \frac{25}{21}\]

\[y = - \frac{25}{21} - \frac{45}{14}\]

\[y = \frac{- 50 - 135}{42}\]

\[y = \frac{- (50 + 135)}{42} = - \frac{185}{42}\]

\[y = - 4\frac{17}{42}\]

\[Ответ:\ y = - 4\frac{17}{42}.\]
