\[а)\ \frac{20y}{36y^{2} - 4} - \frac{2y - 3^{\backslash 6y + 2}}{2 - 6y} = \frac{5 - 2y^{\backslash 6y - 2}}{6y + 2}\]
\[ОДЗ:\ \ \ y \neq \pm \frac{1}{3}.\]
\[24y^{2} - 28y + 4 = 0\ \ \ \ \ \ \ |\ :4\]
\[6y^{2} - 7y + 1 = 0\]
\[D = 49 - 24 = 25\]
\[y_{1} = \frac{7 + 5}{12} = 1;\ \ \ \ \ \]
\[y_{2} = \frac{7 - 5}{12} = \frac{2}{12} = \frac{1}{6}.\]
\[Ответ:y = \frac{1}{6};\ \ y = 1.\]
