若x+y+z=3y=2z,则x/x+y+z=?
若x,y,z成等差数列,则(z-x)^2-4(x-y)(y-z)=
若x,y,z成等差数列,则(z-x)^2-4(x-y)(y-x)=
若x/2=y/3=z/4,则3x-2y+5z/x+y+z=
若(4x-3y-3z)^2+|x-3y-z|=0 且xyz不等于0 则4x+y-z/x+y+z 的值
若4x-3y-6z=0,x+2y-7z=0,则x+y+z/3x-y+z=?
若x/2=y/3=z/4,则x+y+z/x=多少?
若x/2=y/3=z/4则3x-2y+5z/x+y+x=
x+2y=3x+2z=4y+z 求x:y:z
x+y/2=z+x/3=y+z/4 x+y+z=27
x/6=y/4=z/3,则(x+3y)/(3y-2z)
如果x:y=2:3,y:z=4:3,则x:y:z=
若x/4=y/4=z/5,则x+y/x-2y+3z=
若x/3=y/4=z/5则x+y/x-2y+3z=?
若2x+5y+4z=0 ,3x+y=0;则x+y-z=?
若x/2=y/3=z/4 则2x+3y/z 等于?
三元一次方程组题目x+y-z=11 y+z-x=5 x-y+z=1x+y=4 y+z=3 x+z=5若已知x-3y+2z=0 2x+3y-8z=0, 且xyz≠0,则x:y:z=
已知:4x-5y+2z=0 x+4y-3z=0则:(x*x+y*y+z*z)/(x*y+y*z+z*x)=____.
