已知4x-3y-3z=0,x-3y-z=0,求3x-2z+y/-x+y+z的值.﹙x,y,z均不为0)已知4x-3y-3z=0,x-3y-z=0,求3x-2z+y/-x+y+z的值.﹙x,y,z均不为
已知4x-3y-3z=0,x-3y-z=0,求3x-2z+y/-x+y+z的值.﹙x,y,z均不为0)
已知4x-3y-3z=0,x-3y-z=0,求3x-2z+y/-x+y+z的值.﹙x,y,z均不为0)
已知4x-3y-3z=0,x-3y-z=0,求3x-2z+y/-x+y+z的值.﹙x,y,z均不为0)
已知x+y+z=0求证x*x*x+y*y*y+z*z*z=3xyz
已知(x+y)(x+z)=x,(y+z)(y+x)=2y,(z+x)(z+y)=3z,求x,y,z
已知 x-3y+z=0 3x-3y-4z=0,则x:y:z=已知x-3y+z=0 3x-3y-4z=0则x:y:z=
已知x-y/x+y=y+z/2(y-z)=z+x/3(z-x),求证8x+9y+5z=0THX..
已知x,y,z 大于0,x+y+z=2,求证 xz/y(y+z)+zy/x(x+y)+yx/z(z+x)大于等于2/3
已知4x-3y+z=0,x+3y-3z=0,则x:y:z=( )
已知{x-3y+2z=0 3x-3y-4z+0,则x:y:z=?
已知4x-3y-3z=0 x-3y-z=0 (1)求x:y:z
已知X-3Y+Z=0 3X-3Y-4Z=0.则X:Y:Z=?
已知x-2y+3z=0,x-3y+4z=0,则x:y:z=
已知2x-y-z=0,3x+4y-2z=0,则x:y:z=?
已知x+4y-3z=0,4x-5y+2z=0,则x:y:z
已知{x-5y+2z=0 3x-5y-4z=0,求x:y:z
已知方程组4x-5y+2z=0 x+2y=3z 则x:y:z
已知x/3=y/4=z/6≠0,求x+y-z/x-y+z的值
已知:4x-5y+2z=0 x+4y-3z=0则:(x*x+y*y+z*z)/(x*y+y*z+z*x)=____.
(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4x-3y-3z=0,① x-3y+z=0,②并且z不等于0,求x:z与y:z
