X/(X+2000)=0.1% 谁会解这个方程?
X/(X+2000)=0.1% 谁会解这个方程?

X/(X+2000)=0.1% 谁会解这个方程?
X/(X+2000)=0.1%
x=(x+2000)*0.1%
x=0.001x+2
0.999x=2
x=2000/999

X/(X+2000)=0.1%
x/(x+2000)=1/1000
1000x=x+2000
999x=2000
x=2000/999

X/(X+2000)=0.1%
X/(X+2000)=1/1000
X^2+2000X-1/1000=0
解得,X=?

x/(x+2000)=1/1000
1000x=x+2000
x=999/2000
