1800/x=1.2×1560/﹙x+2﹚怎么解
1800/x=1.2×1560/﹙x+2﹚怎么解
1800/x=1.2×1560/﹙x+2﹚怎么解
两边同乘x(x+2)得:
1800(x+2)=1.2×1560x
1800x+3600=1872x
72x=3600
x=50

解 1800/x=1872/(x+2),x≠0且x≠-2
1800(x+2)=1872x
3600=72x
x=50
经检验x=50
1800/x=1.2×1560/﹙x+2﹚
1800×(x+2)=1.2×1560×x
1800X+3600=1872X
72X=3600
X=50
1800/x=1872/(x+2)
1800(x+2)=1872x
100(x+2)=104x
100x+200=104x
x=50
1800/x=1.2×1560/﹙x+2﹚怎么解
x+x=() x*x=() x-0.8x=() 1.2*2y=()
f(x)=x^2+x (x
x^2=x
x+x=( ) x*x=( ) x-0.8=( ) 1.2*2y=( )
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平方-x+2=2x/x+1
f(x)=x|x|+2x (x
(X+1)X(X+2)X(X+3)=504
1560-2x=480+x
x+(200-x)+2x=1800 怎么解
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
0.3x+1.2-2x=1.2-27x
一元一次方程 2x+0.2=1.2x-0.6-2.2x
x+2x+3x+4x+5x+6x+7x+8x+9x=9x-8x-7x-6x-5x-4x-3x-2x-x.x等于多少?
先化简再求值√﹙X/x³-2x²﹚÷√x-2/x-2,x=8
若x=3/x,则[(x^2-6x+9)/(x+3)]÷[﹙x-3﹚/﹙x^2+6x+9﹚]=?
