-1/3（6-5x）=8

1 -1/3（6-5x）=8 两边都乘以3,得5x-6=24,x=6
2 (x-2)/2=(2x+3)/5 两边都乘以10,得5x-10=4x+6,得x=16
3 (x+1)/2 -(x-1)/4 =1 两边都乘以4,得2x+2-x+1=4,得x=1
4 2/7（3x+7）=2 - 3/2x 6x/7+2=2-3x/2 6x/7+3x/2=0 得x=0
5 (x+1)/3 -(3x-1)/6 = 2/3 两边都乘以6,2x+2-3x+1=4 得x=-1
6 (2x+1)/3-(3x-1)/4=2 两边都乘以12,8x+4-9x+3=24,得x=-17
6 (x-2)/5 =2-(x+3)/2 两边都乘以10,2x-4=20-5x-15,得x=9/7
7 (2x+1)/3-(10x+1)/6=1 两边都乘以6,4x+2-10x-1=6,得x=-5/6
8 1-1/3（6x+9）=3（x+1/3） 两边都乘以3,3-6x-9=9x+3,得x=-3/5
