解方程,要详细步骤的X/6%1=X/9+1

x=36

x-1/9=1/6 x=1/6+1/9 x=3/18+2/18 x=5/18

即1/(x+3)+2/(x-3)=1/(x+3)(x-3) 两边乘(x+3)(x-3) x-3+2x+6=1 3x=-2 x=-2/3 经检验,x=-2/3是方程的解

9.5-4在除以1.2就OK啦

X-1/9=2,X=2-1/9,X=1又8/9

1/(x-5)-1/(x-6)=1/(x-8)-1/(x-9) 1/(x-5)(x-6)=1/(x-8)(x-9) (x-5)(x-6)=(x-8)(x-9) x^2-11x+30=x^2-17x+72 6x=42 x=7 经检验,X=7是方程的根

12分之1x+9分之1*(10-x)=1 解:1/12x+10/9-1/9x=1 1/9x-1/12x=10/9-1 1/36x=1/9 x=4

x+1.9=2.6 x=0.7

1/12x+30=1/9(x+30) 3x+1080=4(x+30)方程两边都乘以36, 3x+1080=4x+120 x=1080-120 x= 960,

详细步骤写在纸上了
