解分式方程:1/(x-3)+1/(x-7)=1/(x-4)+1/(x-6).解分式方程:1/(x-3)+1/(x-7)=1/(x-4)+1/(x-6).解分式方程:1/(x-3)+1/(x-7)=1/
解分式方程:1/(x-3)+1/(x-7)=1/(x-4)+1/(x-6).
解分式方程:1/(x-3)+1/(x-7)=1/(x-4)+1/(x-6).
解分式方程:1/(x-3)+1/(x-7)=1/(x-4)+1/(x-6).
1/(x-3)+1/(x-7)=1/(x-4)+1/(x-6).
1/(x-3)-1/(x-4)=1/(x-6)-1/(x-7)
(x-4-x+3)/(x-3)(x-4)=(x-7-x+6)/(x-6)(x-7)
-1/(x-3)(x-4)=-1/(x-6)(x-7)
(x-6)(x-7)=(x-3)(x-4)
x²-13x+42=x²-7x+12
-6x=-30
x=5
检验：x=5是方程的根
解分式方程：(x+1)/(x+2)+(x+6)/(x+7)=(x+2)/(x+3)+(x+5)/(x+6)
解分式方程: (x-1)/(x-2)+(x-6)/(x-7)=(x-2)/(x-3)+(x-5)/(x-6)
1/x+6+1/x+4=1/x+7+1/x+3 解分式方程
解分式方程:1/(x-3)+1/(x-7)=1/(x-4)+1/(x-6).
解分式方程:1/(x+2) + 1/(x+7) = 1/(x+3) + 1/(x+6)
