若|x-1|+|y+4|+|z-3|=0 试求(x+3)乘以(y-1)乘以(z+2)的值
若|x-1|+|y+4|+|z-3|=0 试求(x+3)乘以(y-1)乘以(z+2)的值
若|x-1|+|y+4|+|z-3|=0 试求(x+3)乘以(y-1)乘以(z+2)的值
|x-1|+|y+4|+|z-3|=0
|x-1|=0,|y+4|=0,|z-3|=0
x=1,y=-4,z=3
(x+3)(y-1)(z+2)
=(1+3)(-4-1)(3+2)
=4*(-5)*5
=-100
由已知得x=1,y=-4 z=3。
(x+3)×(y-1)×(z+2)
=(1+3)×(-4-1)×(3+2)
=4×(-5)×5
=-100
若|x+3|+|y-2|+|2×z+1|=0求(x×z-y×z)(y-x+z)的值
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=
若有理数x、y、z满足等式(x-1)^2+(2x-y)^4+|x-3z|=0,求x、y、z的值
若{x-3y+z=0,3x+3y-4z=0,则x:y:z=?
若实数XYZ满足2|x-y|+√2y+z+z方-z+1//4=0 求X+Y+Z 2y+z在根号里
已知4x-3y-3z=0 x-3y-z=0 (1)求x:y:z
若x/2=y/3=z/4不等于0,求x+y+z/x+y-z的值
3X+Y+Z=0,2X-Y+3Z=1,X+2Y-Z=4
若xyz≠0且4(x/z)-5(y/z)=-2,(x/z)+4(y/z)=3,求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=?
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.
x+2y-z=-5 x+y+2z=-1 3x+4y-2z=-12x+2y-z=3 2x+y+3z=0 4x+z=-4
已知4x-3y-3z=x-3y+z=0(x、y、z不等于0)(1)求x:y:z (2)求2x+3y-4z/z的值
