已知4x-5z=y-x+6z=x+y+z,xyz不等于0,求x:y:z已知4x-5z=y-x+6z=x+y+z,xyz不等于0,求x:y:z已知4x-5z=y-x+6z=x+y+z,xyz不等于0,求
已知4x-5z=y-x+6z=x+y+z,xyz不等于0,求x:y:z
已知4x-5z=y-x+6z=x+y+z,xyz不等于0,求x:y:z
已知4x-5z=y-x+6z=x+y+z,xyz不等于0,求x:y:z
y-x+6z=x+y+z 得X=5Z/2
把X=5Z/2代人4x-5z=x+y+z中 得Y=3Z/2
x:y:z=(5Z/2):(3Z/2):Z=5:3:2
y-x+6z=x+y+z知-x+6z=x,2x=6z,x:z=3:1
4x-5z=12z-5z=7z
y-x+6z=y-3z+6z=y+3z
y+3z=7z知y=4z y:z=4:1
x:y:z=3:4:1
已知4x-5z=y-x+6z=x+y+z,xyz不等于0,求x:y:z
已知x/2=y/3=z/5,且3x+4z-2y=40,求x、y、z的值﹔详解
已知x:y:z=2:3:4,求(y+z-x):(2z+3x-4y)的值,又知x+y+z=7,求x,y,z.
已知3/2=4/y=5/z不等于0,那么X+y+z/x-y+z=?
已知x/3=y/4=z/5,求(3x+2y-5z)的值(3x+2y-5z)/x+y+z
已知方程组4x-3y-6z=0,x+2y-7z=0,且z≠0,则x+y+3z/4x-y-5z=( )
已知3X=4X,5Y=6Z求X+Y:Y+Z
已知xyz都不为零,且方程组4x-3y-3z=0,x-3y+z=0求x:y:z
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.
已知有理数x、y、z满足x+y/3=y+z/4=z+x/5,且x+y+z=12则x=?y=?z=?
(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)+y/(z+x)+z/(x+y)=1求 (x*x)/(y+z)+(y*y)/(x+z)+(z*z)/(x+y)=?
x-y-z=0 {x+y-3z=4 2x-5y+7z=21 三元一次方程解
