若xyz满足3x+7y+z=1和4x+10y+z=2001,求分式2000x+2000y+2000z/x+3y的值若xyz满足3x+7y+z=1和4x+10y+z=2001,求分式2000x+2000

若xyz满足3x+7y+z=1和4x+10y+z=2001,求分式2000x+2000y+2000z/x+3y的值
若xyz满足3x+7y+z=1和4x+10y+z=2001,求分式2000x+2000y+2000z/x+3y的值

若xyz满足3x+7y+z=1和4x+10y+z=2001,求分式2000x+2000y+2000z/x+3y的值
2式减1式得到x+3y=2000...设为3式..1式减去2倍的3式得到x+y+z的值...带入就可求出
