1-x/5-x-5-x/1-x=8/x2-5x+5 解方程
这是帮我表姐提问的，她已经算出来了，楼下那位答案错了，
答
x+2/x+1-x+4/x+3=x+6/x+5-x+8/x+7
(x+1+1)/(x+1)-(x+3+1)/(x+3)=(x+5+1)/(x+5)-(x+7+1)/(x+7)
(x+1)/(x+1)+1/(x+1)-(x+3)/(x+3)-1/(x+3)=(x+5)/(x+5)+1/(x+5)-(x+7)/(x+7)-1/(x+7)
1+1/(x+1)-1-1/(x+3)=1+1/(x+5)-1-1/(x+7)
1/(x+1)-1/(x+3)=1/(x+5)-1/(x+7)
(x+3)/(x+1)(x+3)-(x+1)/(x+1)(x+3)=(x+7)/(x+5)(x+7)-(x+5)/(x+5)(x+7)
2/(x+1)(x+3)=2/(x+5)(x+7)
(x+1)(x+3)=(x+5)(x+7)
x^2+4x+3=x^2+12x+35
8x=-32
x=-4答案错了，算了，你写的真辛苦，还写错了，请检查一下你的答案，算对了，分就给你吧
