解下列方程，注意：要步骤
x/2-3x-1/3=1
4x-3(20-x)=6x-7(9-x)
1/2(x-1/2(x-1)=2/3x-1
3/2(2/3(x/4-1)-2)-x=2
x-2/4=1-4-3x/6
x/0.7-0.17-2x/0.03=1
急！！！

Answer 1

x/2-3x-1/3=1
-5/2x=4/3
x=-8/15

4x-3(20-x)=6x-7(9-x)
7x-60=15x-63
8x=3
x=3/8

1/2(x-1/2(x-1))=2/3x-1
1/4x+1/4=2/3x-1
5/12x=2
x=5/24

3/2(2/3(x/4-1)-2)-x=2
-3/4x-2=2
x=-16/3

x/0.7-0.17-2x/0.03=1
10/7x-17/100-200/3x=1
-1370/21x=83/100
x=-1743/137000
