若abc=1,解方程:2ax/ab+a+1+2bx/bc+b+1+2cx/ca+c+1=1
若abc=1,解方程:2ax/ab+a+1+2bx/bc+b+1+2cx/ca+c+1=1

若abc=1,解方程:2ax/ab+a+1+2bx/bc+b+1+2cx/ca+c+1=1
2ax/(ab+a+1)+2bx/(bc+b+1)+2cx/(ca+c+1)=1
2ax/(ab+a+abc)+2bx/(bc+b+1)+2cx/(ca+c+1)=1
2x/(b+1+bc)+2bx/(bc+b+1)+2cx/(ca+c+1)=1
2x(1+b)/(bc+b+1)+2cx/(ca+c+1)=1
[2x(abc+b)/(bc+b+abc)+2cx/(ca+c+1)=1
[2x(ac+1)/(c+1+ac)]+[2cx/(ca+c+1)]=1
2x(ac+1+c)/(ca+c+1)=1
2x=1
x=1/2

X=-6/5

x=-1.2/0.5
