10/(100-X)*100%=12%等多少?

10/(100-X)*100%=12%等多少?
10/(100-X)*100%=12%
10/(100-X)=0.12
10=(100-X)*0.12
10=12-0.12X
0.12X=2
X=100/6

10/(100-X)*100%=12%
10/(100-x)=12/100
12(100-x)=1000
1200-12x=1000
12x=200
x=50/3

X=50/3

10/(100-X)*100%=12%
10/(100-X)=0.12
10=(100-X)*0.12
10=12-0.12X
0.12X=2
X=100/6
