\[\frac{5}{y + 3} - \frac{3}{y} = \frac{2 - y}{y^{2} + 3y}\]
\[ОДЗ:\ \ y
eq 0;\]
\[\ \ \ \ \ \ \ \ \ \ \ y
eq - 3\]
\[\frac{5y - 3 \cdot (y + 3)}{y² + 3y} = \frac{2 - y}{y² + 3y}\]
\[5y - 3y - 9 = 2 - y\]
\[2y - 9 = 2 - y\]
\[3y = 11\]
\[y = \frac{11}{3}\]
\[y = 3\frac{2}{3}\]
\[Ответ:\ \ y = 3\frac{2}{3}.\]
