1-6分之2y-5=2分之3-y1-6分之2y-5=2分之3-y1-6分之2y-5=2分之3-y答:1-6分之2y-5=2分之3-y1-(2y-5)/6=(3-y)/2两边同乘以6:6-(2y-5)=

1-6分之2y-5=2分之3-y
1-6分之2y-5=2分之3-y

1-6分之2y-5=2分之3-y
答:
1-6分之2y-5=2分之3-y
1-(2y-5)/6=(3-y)/2
两边同乘以6:
6-(2y-5)=3(3-y)
6-2y+5=9-3y
11-2y=9-3y
移项得:
3y-2y=9-11
y=-2

1-(2y-5)/6=(3-y)/2
6-(2y-5)=3*(3-y)
11-2y=9-3y
y=-2
