如果x+4/3=y+z/2=z+8/4,且x+y+z=12,求x,y,z的值.
如果x+4/3=y+z/2=z+8/4,且x+y+z=12,求x,y,z的值.
如果x+4/3=y+z/2=z+8/4,且x+y+z=12,求x,y,z的值.
x+4/3=z+8/4,x=z+2/3
y+z/2=z+8/4,y-z/2=2,y=z/2+2
z+2/3+z/2+2+z=12
z+z/2+z=12-2/3-2
5z/2=28/3
z=56/15
y=28/15+2=58/15
x=56/15+2/3=66/15=22/5
如果x+4/3=y+z/2=z+8/4,且x+y+z=12,求x,y,z的值.
如果x/2=y/3=z/4,且x+y+z=18,那么x+y-z=?
如果x/2=y/3=z/4,求(2x-y+3z)/(x+y-z)的值
如果x:y=2:3,y:z=4:3,则x:y:z=
如果x:y=3:2,y:Z=4:2,那么x:y:Z=
(4x-2y-z)-{5x-[8y-2z-(x-2y)]-x-(3y-10z)}=?
x+y/2=z+x/3=y+z/4 x+y+z=27
x+2y=3x+2z=4y+z 求x:y:z
(x*x+2)(y*y+4)(z*z+8)=64xyz,求x,y,z
如果3/x+4=2/y+3=4/z+8,x+y+Z=12,x,y,z的值是多少?
如果x+4/3=y+3/2+z+8/4,且x+y+z=12,求x,y,z的值.
(4x-2y-z)-{5x-[8y-2z-(x+y)]-2(3y-10z)}=?好难啊
x=y/z=z/3,x+y+z =12,求2x+3y+4z是多少,
2x+z=10 x+y-z=4 3x-y-z=0
x:y:z=3:4:5 2x-3y+2z=8 x-y-2z=?
三元一次方程 X+Y+Z=6 2X+3Y-Z=4 3X-Y+Z=8
x+y+z=-1 4x-2y+3z=5 y-z=8-2x
2x+3y+z=8 4x-y-z=10 x+2y-z=1
