1 - （x - 1）/ 2 = x / 3 + 1
解：两边乘以 6 得：
6 - 3（x - 1）= 2 x + 6
6 - 3 x + 3 = 2 x + 6
9 - 1 - 6 = 2 x + 3 x
2 = 5 x
x = 2 ÷ 5
x = 2 / 5
x = 0.4

两边乘6
6-3(x-1)=2(x+1)
6-3x+3=2x+2
2x+3x=6+3-2
5x=7
x=7÷5
x=1又5分之2
两边乘6
6-3x+3=2x+2
-5x=-7
x=1.4
1-(x-1)/2=(x+1)/3
6-3x+3=2x+2
5x=7
x=7/5
1-2分之x-1=3分之x+1
1-(x-1)/2=(x+1)/3
6-3(x-1)=2(x+1)
6-3x+3=2x+2
5x=9-2=7
x=7/5
2分之1
