问题求解初一数学题谢谢
1/(x+5)+1/(x+8)=1/(x+6)+1/(x+7)
1/(x+5)+1/(x+8)=1/(x+6)+1/(x+7)
答案解：1/(x+5)+1/(x+8)=1/(x+6)+1/(x+7)
1/(x+5)-1/(x+6)=1/(x+7)-1/(x+8)
1/[(x+5)(x+6)]=1/[(x+7)(x+8)]
(x+5)(x+6)=(x+7)(x+8)
11x+30=15x+56
x=-13/2
1/(x+5)-1/(x+6)=1/(x+7)-1/(x+8)
1/[(x+5)(x+6)]=1/[(x+7)(x+8)]
(x+5)(x+6)=(x+7)(x+8)
11x+30=15x+56
x=-13/2
