解方程：（x-8）/(x-3)-(x-9)/(x-4)=(x+7)/(x+8)-(x+2)/(x+3)解方程：（x-8）/(x-3)-(x-9)/(x-4)=(x+7)/(x+8)-(x+2)/(x+
解方程：（x-8）/(x-3)-(x-9)/(x-4)=(x+7)/(x+8)-(x+2)/(x+3)
解方程：（x-8）/(x-3)-(x-9)/(x-4)=(x+7)/(x+8)-(x+2)/(x+3)
解方程：（x-8）/(x-3)-(x-9)/(x-4)=(x+7)/(x+8)-(x+2)/(x+3)
(x+8)/(x-3)-(x-9)/(x-4)=(x+7)/(x+8)-(x+2)/(x+3)
[（x-8）(x-4)-(x-9)(x-3)]/(x-3)(x-4)
=[(x+7)(x+3)-(x+2)(x+8)]/(x+8)(x+3)
解得5/(x-3)(x-4)=5/(x+8)(x+3),
所以(x-3)(x-4)=(x+8)(x+3),
解得x=-2/3
