x/0.05/2=4500-x/0.02/4x+24/2*0.5=x x/0.05/2=4500-x/0.02/4 x+24/2*0.5=xx/0.05/2
x/0.05/2=4500-x/0.02/4 x+24/2*0.5=x
x/0.05/2=4500-x/0.02/4 x+24/2*0.5=x
x/0.05/2=4500-x/0.02/4 x+24/2*0.5=x
2x/0.05=4500-4x/0.02
2x/5=450000-4x/2
12x/5=450000
x=187500
2X(x÷0.05)=(4500-x)÷0.02
x/0.05/2=4500-x/0.02/4 x+24/2*0.5=x
f(x)=x^2+x (x
matlab中f=@(x)[x(2);x(3);0.05*x(1)*(x(2)+x(3))]中@(x)什么意思
x^2=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/(2*0.05)=(4500-X)/(4*0.
解方程:x除以0.05除以2=(4500-x)除以0.02除以48x=10(4500-x)
x/x平方-x+2=2x/x+1
f(x)=x|x|+2x (x
(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)/0.3-2x=(0.1x+0.2)/0.05
3/0.2x-0.1-0.05/(x+2)%=0.1x
0.05x-0.12/0.03=x-2
5Y-1/6=7/3 3X-1/4=1-X+1/4 X/0.3-0.03+0.05X/0.02+4=0 X+4/5-(X-5)=X+3/3-X-2/2
x+2x+3x+4x+5x+6x+7x+8x+9x=9x-8x-7x-6x-5x-4x-3x-2x-x.x等于多少?
