X/3=Y/4=Z/5X+Y+Z=24X/3=Y/4=Z/5X+Y+Z=24X/3=Y/4=Z/5X+Y+Z=24令X/3=Y/4=Z/5=K则X=3K,Y=4K,Z=5KX+Y+Z=243K+4K+

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~_~
