1/2{1/3[1/4(x+1/5-1)-6]+x}=1小括号里的是5分之x+1再-1
1/2{1/3[1/4(x+1/5-1)-6]+x}=1
小括号里的是5分之x+1再-1
1/2{1/3[1/4(x+1/5-1)-6]+x}=1小括号里的是5分之x+1再-1
1/2{1/3[1/4(x+1/5-1)-6]+x}=1
1/3{1/4[(x+1）/5-1]-6}+x=2
1/4[(x+1）/5-1]-6+3x=6
1/4[(x+1）/5-1]=12-3x
(x+1）/5-1=48-12x
(x+1）/5=49-12x
x+1=245-60x
61x=244
1/2{1/3[1/4(x+1/5-1)-6]+x}=1
1/3[1/4(x+1/5-1)-6]+x=2
1/4(x+1/5-1)-6]+3x=6
(x+1/5-1)-6+12x=24
(x+1/5-1)+12x=30
(x+1)/5-1+12x=30
(x+1)/5+12x=31
x+1+60x=15
61x=154
x=154/61

做法是先将分数乘到右边去例如：
第一步 1/3[1/4(x+1/5-1)-6]+x=2 可得 1/3[1/4(x+1/5-1)-6]=2-x
第二步 1/4(x+1/5-1)-6=6-3x 可得 1/4(x+1/5-1)=12-3x
第三部 x+1/5-1=48-12x 可得 （x+1）/5=49-12x
第四步 x+1=5*49-60x 可得 61x=244 即 x=4
X=241/61
X-1-4*5*6+3*4*5*X=2*3*4*5
x=4
