5乘以3分之1x-1-2x=1怎么解

（2x-5）/(x-2)(x-3)-1/(x-3)=（2x-5）/(x-2)(x-3)-(x-2)/(x-2)(x-3)=（2x-5-x+2)/(x-2)(x-3)=（x-3)/(x-2)(x-3)=

题目应是x-1分之1加（x-1）乘以（x-2）分之1加（x-2）乘以（x-3）分之1+……+（x-99）乘以（x-100）分之1=11/(x-1)+1/(x-1)(x-2)+1/（x-2）(x-3)+

(x/5-3-2x)×0.5=1;x/5-3-2x=2;-9x/5=5;x=-25/9;很高兴为您解答,skyhunter002为您答疑解惑如果本题有什么不明白可以追问,再问：饿...是1/5x减0.

首先计算(x+3)/(x^2-1)乘以（x^2-2x+1）/(x^2+4x+3),分解因式可以得到(x+3)/(x+1)(x-1)乘以(x-1)^2/(x+3)(x+1),约分后等于(x-1)/(x+

0.9(X-4)=19.8x-4=22;x=26;计算'49.5乘以10又5分之3-(50-2分之1)乘以5分之3=49.5×(10+3/5)-49.5×(3/5)=49.5×(10+3/5-3/5)

原式=x/4-1-3=x/4-4=-1/2-4=-9/2

)【(x²-2x+1)/(x²-1)】÷【(x-1)/(x²+x)】=【(x-1）²/(x+1)（x-1)】÷【(x-1)/x(x+1)】=【(x-1）/(x+

原式=x/(2x-3)÷3/(2x+3)(2x-3)*1/(x+3)=x/(2x-3)*(2x+3)(2x-3)/3*1/(x+3)=x(2x+3)/[3(x+3)]=2*(4+3)/3*(2+3)=

X^5分之1-X吧（1-x^2）=(1-X)(1+X)（x^3+x^2）=x^2（X+1）约分等于x^2分之(1-X)再乘x^2分之1乘x分之1

原方程可化为：400*(0.75x)-99x=0.1300x-99x=0.1201x=0.12010x=1解得：x=2010分之1

解:2*[1-1/3(2x-1/3)]=3*[x/6-1/2*(-5x-10/3)]2*[1-2/3+1/9]=3*[x/6+5/2x+5/3]2*[1-2/3*x+1/9]=x/6+5/2*x+5/

原式=[3x/(x-1)-x/(x+1)]×[(x²-1)/x]={3x(x+1)/[(x-1)(x+1)]-x(x-1)/[(x-1)(x+1)]}×[(x-1)(x+1)/x]=[3x(

4分之1乘以X乘以5分之3等于30分之17X/4*3/5=17/303X/20=7/303X*30=20*790X=140X=14/9X=1又9分之5

把每个式子因式分解x的方+5x+4=（x+1）(x+4)x方-5x+6=(x-2)(x-3)………………

原式=(x^2-8x+16)^3(x+1)^6/(x^2-2x+1)^3(x-4)^4(x+2)^2=(x-4)^6(x+1)^6/(x-1)^6(x-4)^4(x+2)^2=(x-4)^2(x+1)

1乘以2分之x+2乘以3分之x+.+2012乘以2013分之x=2012(1-1/2+1/2-1/3+……+1/2012-1/2013)x=2012(1-1/2013)x=20122012/2013x

原式=5x根号(xy)/3根号(y/x)*1/3根号(x/y)=5/9*根号(xy*x/y*x/y)=5x/9y根号(xy)

观察x/(1×2)=x/2而x-x/2=x/2则有x/(1×2)=x-(x/2)x/(2×3)=x/6而(x/2)-(x/3)=x/6则有x/(2×3)=(x/2)-(x/3)同理x/(3×4)=(x
