代數題(急)

y-6=y×3%
y×3%-y=-6
6=y-y×3%
6=0.97y
y=6/0.97
~6.1856

2006-11-21 19:28:41 補充：
是6.1856不是其他人說的61.856

y-6= y×3%
y-6= 3/100y
-6 = -97/100y
y = 600/97

y×3%-y=-6
6=y-y×3%
6=0.97y
y=6/0.97
=6.1856 .....
~6.186

y-6=y×3%
-6=30/100y+y
-6=(30+100)/100y
-6=130/100y
-6(100/130)=y
y= -4/8/13

y-6=y×3%

y-6=yx3%÷3%

y-6x100÷3=y

y-200=y

y=y+200


I hope I 'm correct

y-6=yx3%
y-6=0.03y
y-0.03y=6
y(1-0.03)=6
0.97y=6
y=6.1855

y-6=y×3%
y-6=0.03y
y(1-0.03)=6
y = 6/0.97

y=61.855670103092783505154639175258
