6000-6000X-(6000-6000X)X=48606000-6000X-(6000-6000X)X=48606000-6000X-(6000-6000X)X=48606000-6000X-(6
6000-6000X-(6000-6000X)X=4860
6000-6000X-(6000-6000X)X=4860
6000-6000X-(6000-6000X)X=4860
6000-6000X-(6000-6000X)X
=(6000-6000X)(1-x)
=6000(1-x)^2
=4860
所以
(1-x)^2
=0.81
所以
1-x=±0.9
所以x=0.1或x=1.9
600/x+6000/2x=9
6000-6000X-(6000-6000X)X=4860
53.96*x*x*x-359.55*x*x-2085.66+6000=0 求X
(10+x)(500-20x)=6000
(10+X)(500-20X)=6000 ----------------------X=?
1140+1200x+6000x²=0 x=?
百分之45X+百分之45X+3000=X-6000
x-[(x-5000)*0.944]=6000,请问怎样求X?
6000/x=10800/2x+20 x=?
设总人数为x,则 0.2x+6000+(0.2x+6000-2000)+1/3x=x
6000÷x-4=6000÷1.5x
(60+x)(300-10x)-40(300-10x)怎么化简成-10X^2+100x+6000
1/5X+1500+4500=X X-1/5X=6000 4/5X=6000 X=7500
二元一次方程,6000x+5000(36-x)=10 0000 求x=? 6000x +2000(36-x)=10 0000求x=?
(10+x)(500-20x)=6000
如何解6000/x+40-80=5000/x+60
(500-2x)(10+x)=6000,解这个方程
(10+x)(500-20x)=6000
