1/2{1/3[1/4(1/5x-1)-6]+4}=1
{1/3[1/4(1/5x-1)-6]+4}=2
[1/4(1/5x-1)-6]+4=6
[1/4(1/5x-1)-6]=2
1/4(1/5x-1)=8
(1/5x-1)=32
1/5x=33
X=165
3/2[2/3(1/4x+1)+2]-2又1/2=2x/3
{3[2/3(1/4x+1)+2]-5}/2=2x/3
9[2/3(1/4x+1)+2]-5=4x
9[2/3(1/4x+1)+2]=4x+5
9[(1/6x+2/3)+2]=4x+5
(3/2x+6)+18]=4x+5
3/2x+24=4x+5
5X/2=19
X=38/5
