Ответ:
\[\frac{27}{x^{2} + 3x} - \frac{2}{x} = \frac{3}{x^{2} - 3x}\]
\[\frac{27^{\backslash x - 3}}{x(x + 3)} - \frac{2^{\backslash x^{2} - 9}}{x} = \frac{3^{\backslash x + 3}}{x(x - 3)}\]
\[ОДЗ:\ \ x \neq 0;\ \ x \neq \pm 3.\]
\[27x - 81 - 2x^{2} + 18 = 3x + 9\]
\[2x^{2} - 24x + 72 = 0\ \ \ \ |\ :2\]
\[x^{2} - 12x + 36 = 0\]
\[(x - 6)^{2} = 0\]
\[x - 6 = 0\]
\[x = 6.\]
\[Ответ:x = 6.\]
