2. 解下列方程:
(1)$\frac{x - 2}{x + 3} = \frac{1}{2}$; (2)$\frac{1}{x - 2} = \frac{3}{x}$;
(3)$\frac{2x}{x - 1} + \frac{2}{x + 2} = 2$; (4)$\frac{3 - 2x}{1 - x} - 1 = \frac{x + 2}{x - 3}$.
(1)$\frac{x - 2}{x + 3} = \frac{1}{2}$; (2)$\frac{1}{x - 2} = \frac{3}{x}$;
(3)$\frac{2x}{x - 1} + \frac{2}{x + 2} = 2$; (4)$\frac{3 - 2x}{1 - x} - 1 = \frac{x + 2}{x - 3}$.
答案
3.(1)解方程:$\frac{1}{(x - 1)(x - 2)} = \frac{1}{(x - 4)(x - 5)}$.
(2)解方程:$\frac{x}{x - 1} - \frac{x - 1}{x - 2} = \frac{x - 3}{x - 4} - \frac{x - 4}{x - 5}$.
(2)解方程:$\frac{x}{x - 1} - \frac{x - 1}{x - 2} = \frac{x - 3}{x - 4} - \frac{x - 4}{x - 5}$.
