8) 2x - 1 = 2x + 1_3x-1 5x - 146;

Решение: $$\frac{2x-1}{5x-1} = \frac{2x+1}{4} - \frac{3x-1}{6}$$ ОДЗ: $$x
eq \frac{1}{5}$$ $$\frac{2x-1}{5x-1} = \frac{3(2x+1) - 2(3x-1)}{12}$$ $$\frac{2x-1}{5x-1} = \frac{6x+3 - 6x+2}{12}$$ $$\frac{2x-1}{5x-1} = \frac{5}{12}$$ $$12(2x-1) = 5(5x-1)$$ $$24x - 12 = 25x - 5$$ $$-x = 7$$ $$x = -7$$ Ответ: x=-7
