\[\frac{2}{x - 5} - \frac{4}{x + 5} = \frac{3}{x^{2} - 25}\]
\[ОДЗ:\ \ x - 5
eq 0;x
eq 5\]
\[\ \ \ \ \ \ x + 5
eq 0;\ \ x
eq - 5\]
\[\frac{2 \cdot (x + 5) - 4 \cdot (x - 5)}{(x - 5)(x + 5)} =\]
\[= \frac{3}{(x - 5)(x + 5)}\]
\[2x + 10 - 4x + 20 = 3\]
\[- 2x = - 27\]
\[x = 13,5\]
\[Ответ:x = 13,5.\]
