解方程：(x-4)/(x-5)-(x-5)/(x-6)=(x-7)/(x-8)-(x-8)/(x-9)
解方程：(x-4)/(x-5)-(x-5)/(x-6)=(x-7)/(x-8)-(x-8)/(x-9)
解方程：(x-4)/(x-5)-(x-5)/(x-6)=(x-7)/(x-8)-(x-8)/(x-9)
(x-4)/(x-5)-(x-5)/(x-6)=(x-7)/(x-8)-(x-8)/(x-9)
1+1/(x-5)-1-1/(x-6)=1+1/(x-8)-1-1/(x-9)
1/(x-5)-1/(x-6)=1/(x-8)-1/(x-9)
通分：
-1/[（x-5）(x-6)]=-1/[（x-8）(x-9)]
（x-5）(x-6)=（x-8）(x-9)
x^2-11x+30=x^2-17x+72
6x=42
x=7
=>
1/(x-5) - 1/(x-6) = 1/(x-8) - 1/(x-9)
=>
1/(x-5) + 1/(x-9) = 1/(x-6) + 1/(x-8)
=>
(2x-14)/(x-5)(x-9) = (2x-14)/(x-6)(x-8)
=>
x = 7
或
(x-5)(x-9) = (x-6)(x-8)
=>无解
所以
x=7
解方程；x/x-4=5x/x-2
解方程：5x(x+7)(x+4)=5x(x的平方+11x)
5x(x+7)(x+4)=5x(x^2+11X)解方程,
解方程 x(2x-4)+3x(x-1)=5x(x-3)+8
解方程：x(3x-4)+2x(x+7)=5x(x-7)+90
解方程5x-4=-x
4x-5=x解方程
解分式方程：(x-4)/(x-5)+(x-8)/(x-9)=(x-7)/(x-8)+(x-5)/( x-6)
解方程:x-4/x-5 -x-5/x-6=x-7/x-8 -x-8/x-9
解方程：(x-4)/(x-5)-(x-5)/(x-6)=(x-7)/(x-8)-(x-8)/(x-9)
解分式方程（X-4)/(X-5)-(X-5)/(X-6)=(X-7)/(X-8)-(X-8)/(X-9)
求方程解x-5/x-4+x-9/x-8=x-8/x-7+x-6/x-5
解因式方程：x-4/x-5+x-8/x-9=x-7/x-8+x-5/x-6
解方程(x-4)/(x-5)+(x-8)/(x-9)=(x-7)/(x-8)+(x-5)/(x-6)
解方程：(x+3)/(x+2)-(x+4)/(x+3)=(x+5)/(x+4)-(x+2)/(x+1)
解分式方程 x-7/x-9+x-3/x-5=x-4/x-6+x-6/x-8
解方程 x-7/x-9+x-3/x-5=x-4/x-6+x-6/x-8
解方程 x+2/x+1+x+8/x+7=x+6/x+5+x+4/x+3
