+34 1/16 是什么东东?
题不对的话没人能帮你解.
不过这道题的解题思路应该是:
把等式写成(x-1/4)^2+(y+3)^2+(z-5)^2=0
得到 x=1/4 ,y=-3 ,z=5 ...
已知x、y、z满足方程组:x+y-z=6;y+z-x=2;z+x-y=0 求x、y、z的值
已知X.Y.Z满足方程组,X+y-Z=6y+z-x=2z+x-y=0求X.Y.Z的值
已知实数x y z满足x/(x+1)=y/(y+2)=z/(z+3)=(x+y+z)/3,求x+y+z的值
已知实数x y z满足x/(x+1)=y/(y+2)=z/(z+3)=(x+y+z)/3,求x+y+z的值
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x,y,z满足x+y+2z=1,x²+y²+6z+1.5=0,求x,y,z的值
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.
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>0,xyz(x+y+z)=1,求证(x+y)(x+z)>=2
1、y-x/x²-y²2、(x-y)(y-z)(z-x)/(z-y)(y-x)(x-z)
已知x,y,z满足方程组{x+y-z=6{y+z-x=2{z+x_y=0,求x,y,z的值
已知x-2y=3,x-y+z=4,x+6y+2z=-1,求x,y,z分别为多少?
已知x+2y-3z=0,5x-6y+7z=1;则x:y:z=?把“5z-6y+7z=1”改成“5x-6y+7z=0”
已知x+y+z=6,x^2+y^2+z^2=12,求x,y,z的值
已知;根号x+根号y-1+根号z-2=1/2(x+y+z),求x、y、z
已知x:y:z=1:3:5,求(2x+3y-z)/(x+y-2z)的值
已知(1)X-Y+Z=0 (2)X+2Y-3Z=0 求X:Y:Z
已知2x+5y+4z=6 3x+y-7z=-4求x+y-z
