(4(4x-3)-1)/4x-3 + (5(8x-9)+2)/(8x-9) =(4(8x-7)-2)/(8x-7) +(5(4x-5)+1)/(4x-5)
整理得
2/(8x-9) - 1/4x-3 = 1/(4x-5) - 1/(8x-7)
两边分别通分得
1/(4x-5)(8x-7) = 1/(8x-9)(4x-3)
化简
(4x-5)(8x-7) = (8x-9)(4x-3)
化简
x=1

原式可化为 4 - 1/(4x-3)+ 5 + 2/(8x-9)=4 - 2/(8x-7)+ 5 + 1/(4x-5)
2/(8x-9)- 1/(4x-3)= 1/(4x-5) - 2/(8x-7)
3 /[(8x-9)*(4x-3) ] = 3/[(4x-5)*(...

全部展开

原式可化为 4 - 1/(4x-3)+ 5 + 2/(8x-9)=4 - 2/(8x-7)+ 5 + 1/(4x-5)
2/(8x-9)- 1/(4x-3)= 1/(4x-5) - 2/(8x-7)
3 /[(8x-9)*(4x-3) ] = 3/[(4x-5)*(8x-7)]
(8x-9)*(4x-3) = (4x-5)*(8x-7)
27- 60*x = 35 - 68*x
求得 x=1
