一道数学分式方程(x-4)/(x-3)-(x-6)/(x-5)=(x-8)/(x-7)-(x-10)/(x-9)

一道数学分式方程(x-4)/(x-3)-(x-6)/(x-5)=(x-8)/(x-7)-(x-10)/(x-9)
一道数学分式方程
(x-4)/(x-3)-(x-6)/(x-5)=(x-8)/(x-7)-(x-10)/(x-9)

一道数学分式方程(x-4)/(x-3)-(x-6)/(x-5)=(x-8)/(x-7)-(x-10)/(x-9)
(x-3-1)/(x-3)-(x-5-1)/(x-5)=(x-7-1)/(x-7)-(x-9-1)/(x-9)
1-1/(x-3)-1+1/(x-5)=1-1/(x-7)-1+1/(x-9)
1/(x-7)+1/(x-5)=1/(x-3)+1/(x-9)
(x-5+x-7)/(x-7)(x-5)=(x-3+x-9)/(x-3)(x-9)
(2x-12)/(x^2-12x+35)=(2x-12)/(x^2-12x+27)
(2x-12)[1/(x^2-12x+35)-1/(x^2-12x+27)]=0
因为x^2-12x+35不等于x^2-12x+27
所以1/(x^2-12x+35)-1/(x^2-12x+27)不等于0
所以2x-12=0
x=6
经检验
x=6是方程的解
