Question

帮偶做一下哈,.（急用,快哦,有甲、乙、丙三个箱子,各装有若干个球.先从甲箱中取出一批球放进乙和丙的箱中,所放之数分别是

Answer 1

解设甲,乙,丙箱中开始各有球x y z个

x y z

(x-y-z) (2y) (2z)[第一次取放]

2(x-y-z) 2y-2z-2(x-y-z) (4z)[第二次取放]

4(x-y-z) 2(3y-z-x) { 4z-2(x-y-z)-(3y-z-x)

=(7z-x-y)}[第三次取放]

x+y+z=96*3 (1)

4(x-y-z)=2(3y-z-x) (2)

4(x-y-z)=(7z-x-y) (3)

解之得x=52 y=28 z=16
