0.25*X+(150-X)*0.1=150*0.150.25*X+(150-X)*0.1=150*0.150.25*X+(150-X)*0.1=150*0.150.25*X+(150-X)*0.1=
0.25*X+(150-X)*0.1=150*0.15
0.25*X+(150-X)*0.1=150*0.15
0.25*X+(150-X)*0.1=150*0.15
0.25*X+(150-X)*0.1=150*0.15
0.25*X+150*0.1-0.1*X=150*0.15
15+0.15*X=150*0.15
0.15*100+0.15*X=150*0.15
100+X=150
X=50
0.25*X+(150-X)*0.1=150*0.15
0.25x+15-0.1x=22.5
0.15x=7.5
x=50 .
[0.25*X+(150-X)*0.1]*100=(150*0.15)*100
25X+(150-X)*10=150*15
25X+150*10-10X=150*15
25X-10X=150*15-150*10
15X=150*5
X=150*5/15=50
x-0.25x+1=10.4x+0.25x-1
x=1+0.5x+0.25x+0.125x+0.0625x求x的值
X(X-1)=X
x>=1,x
x/x-2+x-9/x-7=x+1/x-1+x-8/x-6,
x/x-2+x-9/x-7=x+1/x-1+x-8/x-6,
x*x*x*x+2008x*x+2007x+2008(提示：x*x*x-1=（x-1）*（x*x+x+1））
0.25*X+(150-X)*0.1=150*0.15
x/x平方-x+2=2x/x+1
(X+1)X(X+2)X(X+3)=504
一个“整式的乘法”的问题请先阅读下列解题过程,再仿做下面的问题.已知X*X + X - 1=0,求X*X*X + 2*X*X + 3的值.解X*X*X + 2X*X +3=X*X*X +X*X -X +X*X +X +3=X{X*X +X -1} +X*X +X -1 +4=0+0+4=4+ x + X*X + X*X*X=0.+ X*X + X*X*X
x-1/0.25-x/12.5=1.2 x等于多少?
0.3(x+1)+0.25(100-x)=2/5x
2x/0.03+0.25-0,1x/0.02=0.1
100/x+1/2=150/(x+10) x=?
(x+1)/0.3-2x=(0.1x+0.2)/0.05
X+1/0.2-2X=0.1x+0.2/0.03:
(x-0.6)/0.4+x=(0.1x+1)/0.3
