已知Y+X/X=Z+X/Y=X+Y/Z,求X+Y+Z/X+Y+Z的值"
我做过原题的,不过方法忘记了.
X+Y+Z/X+Y+Z=1啊 你搞错了吧
是Y+Z/X=Z+X/Y=X+Y/Z,求X/Y+Z的值" 吧
原式=x+y+z/x=x+y+z/y=x+y+z/z
所以X=Y=Z或X+Y+Z=0
所以X/Y+Z=1/2或-1
这是原题
=1
已知 x/(y+z)+y/(z+x)+z/(x+y)=1求 (x*x)/(y+z)+(y*y)/(x+z)+(z*z)/(x+y)=?
(x+y-z)(x-y+z)=
已知(x+y)(x+z)=x,(y+z)(y+x)=2y,(z+x)(z+y)=3z,求x,y,z
已知 (x+y-z)/z=(x-y+z)/y=(y+z-x)/x,且xyz≠0,求代数式 ((x+y)(y+z)(x+z))/xyz
分式加减法:已知x+y/z=x+z/y=y+z/x(x+y+z≠0),求x+y-z/x+y+z
已知x+y/z=x+z/y=y+z/x(x+y+z≠0),求x+y-z/x+y+z的步骤
已知x+y/z=x+z/y=y+z/x(x+y+z≠0),求x+y-z/x+y+z的步骤
已知:x^2/(z+y)+y^2/(x+z)+z^2/(x+y)=0,求x/(z+y)+y/(x+z)+z/(x+y)的值.
X+Y+Z=?
x/y=(x+z)/(y+z)y/z=(x+y)/(x+z)
已知x+y+z=0求证x*x*x+y*y*y+z*z*z=3xyz
已知(y+z)/x=(z+x)/y=(x+y)/z,则(y+z)/x的值是多少
已知x/(y+z+u)=y/(z+u+x)=z/(u+x+y)=u/(x+y+z)求(x+y)/(z+u)+(y+z)/(x+u)+(z+u)/(x+y)+(u+x)/(y+z)
已知X+Y+Z=0,求(X+Y)(Y+Z)(X+Z)+XYZ的值.
已知x+y+z=0,求(x+y)(y+z)(z+x)+xyz的值
已知x+y+z=0,求(x+y)(y+z)(x+z)+xyz的值
已知:(x+y-z)/z=(x-y+z)/y+(y+z-x)/x,且xyz≠0,求代数式[(x+y)(y+z)(x+z)]/xyz的值已知:(x+y-z)/z=(x-y+z)/y=(y+z-x)/x,且xyz≠0,求代数式[(x+y)(y+z)(x+z)]/xyz的值 题目中写错个等号,汗...
(y+z)/x=(z+x)/y=(x+y)/z求x+y-z/x+y+z的值
