X/3=Y/4=Z/5 X+Y+Z=24
X/3=Y/4=Z/5 X+Y+Z=24
X/3=Y/4=Z/5 X+Y+Z=24
令X/3=Y/4=Z/5=K
则X=3K,Y=4K,Z=5K
X+Y+Z=24
3K+4K+5K=24
12K=24
K=2
X=3K=6
Y=4K=8
Z=5K=10
X/3=Y/4=Z/5=k
x=3k, y=4k, z=5k
∵x+y+z=24
∴3k+4k+5k=24
k=2
∴x=6, y=8, z=10
x=6,y=8,z=10
X/3=Y/4=Z/5
可以设x=3a y=4a z=5a
X+Y+Z=12a=24 a=2
x=6 y=8 z=10
令x/3=y/4=z/5=k,则x=3k,y=4k,z=5k.所以(3+4+5)k=24,k=2,所以方程组的解是x=6,y=8,z=10.
祝你好运~_~
(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
若x:y:z=3:4:5且x+y+z=24,求x、y、z的值
若x:y:z=3:4:5 x+y+z=24 求x,y,z的值
若X:y:Z=3:4:5,且X+Y+Z=24,求X、Y、Z的值

x+y-z=3 y+z-x=5 z+x-y=7 求x,y,z
(x+y-z)(x-y+z)=
x+y/2=z+x/3=y+z/4 x+y+z=27

(4x-2y-z)-{5x-[8y-2z-(x+y)]-2(3y-10z)}=?好难啊
x+y=5 2x+3y-z=9 x-y+z=4
已知3X=4X,5Y=6Z求X+Y:Y+Z
x,y,z不是0.3z=4y,z=3x求(x+y):(x+z).
