x:y=3:2.5,y:z=1/4:3/8,求x:y:z的最简整数比

x>=y>=z c语言x=3;y=z=4z>=y>=x 这个不是应该等于（z>y&&y=x)||(z>y&&y>x)||(z=y&&y>x)||(z=y&&y=x)这个难道不是1么 符合z=y&&y>x x+y/2=z+x/3=y+z/4 x+y+z=27 x+2y=3x+2z=4y+z 求x:y:z x:y=3:4 y:z=2:1 x+y+z=20 急! 解方程组 1.3(x+y)-4(x-y)=4,x+y/2 + x-y/6 =1 2.5x+4y+z=0,3x+y-4z=11,x+y+z=-2 4x+y+z=-3 2x+3y-4z=-10 x+2y-z=-1 x-y-z=1 2x+y-3z=4 3x-2y-z=-1 已知4x-3y-3z=0 x-3y-z=0 (1)求x:y:z {3X+2Y+Z=4X+Y+Z=102X+3Y-Z=1 x+y-z=6 x-3y+2z=1 3x+2y-z=4 阿 x+y-z=6,x-3y+2z=1,3x+2y-z=4 x+y+z=-5,3x+y+z=1,4x+3y+2z=-2快 3x+2y+z=4 x+y+z=10 2x+3y-z=1 x+y-z=6 x-3y+2z=1 3x+2y-z=4 3X+Y+Z=0,2X-Y+3Z=1,X+2Y-Z=4 x+y-z=6 x-3y+2z=1 3x+y-z=4 x+y+z=6 x+2y+3z=14 y+1=z x+y+z=2 4x+2y+z=4 2x+3y+z=1
