已知4x-5z=y-x+6z=x+y+z,xyz≠0,求x:y::z已知4x-5z=y-x+6z=x+y+z,xyz≠0,求x:y::z已知4x-5z=y-x+6z=x+y+z,xyz≠0,求x:y:
已知4x-5z=y-x+6z=x+y+z,xyz≠0,求x:y::z
已知4x-5z=y-x+6z=x+y+z,xyz≠0,求x:y::z
已知4x-5z=y-x+6z=x+y+z,xyz≠0,求x:y::z
又题意可知:
x+y+z=4x-5z 可以得出 3x=y+6z.(1)
4x-5z=y-x+6z 可以得出 5x=y+11z.(2)
由(2)-(1)得出 2x=5z 即 X=2.5Z.(3)
(3)代入(1)可得 Y=1.5Z
有因为xyz不等0
所以X:Y:Z=2.5:1.5:1
即X:Y:Z=5:3:2
已知3X=4X,5Y=6Z求X+Y:Y+Z
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)=?
已知2x+5y+4z=6 3x+y-7z=-4求x+y-z
已知x/4=y/5=z/6 求x+y+z/3x-2y+z的值
已知x/4=y/5=z/6,求x+y+z/3x-2y+z的值.
(x+y):(y+z):(z+x)=3:4:5 3x+y-z=-4已知(x+y):(y+z):(z+x)=3:4:5 ;3x+y-z=-4求x y z
已知x::y:z=3:4:5,(1)求x+y分之z的值;(2)若x+y+z=6,求x,y,z.
已知4x-3y-6z=0,x+2y-7z=0,求5x+2y-z/2x-3y-10z
已知x/4=y/5=z/6则(x+y)(y+z)=
已知x+y+z=4x-5z=y-x+6z,xyz不等0,求x:y:z
已知4x-5z=y-x+6z=x+y+z,xyz≠0,求x:y::z
已知x:4=y:5=z:6.则x:y:z= (x+y):(y+z)=
(x+y-z)(x-y+z)=
x+y+z=4x-5y=y-x+6z,xyz不等0,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XY=2(X+Y),YZ=4(Y+Z),ZX=5(Z+X),求X,Y,Z已知XY=2(X+Y),YZ=4(Y+Z),ZX=5(Z+X),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
