解答
(1/2)x=(1/3)y=(1/4)z = k
x = 2k,y =3k ,z =4k
x:y:z= 2:3:4
推荐
- 已知x-y+z=0,2x-3y-4z=0,且xyz不等于0,求x平方+y平方+z平方/x平方+y平方-2倍z平方的值
- 由方程组x−2y+3z＝02x−3y+4z＝0，可得x：y：z等于_．
- 已知x/2=y/3=z/4，且xyz≠0，求2x+3y−zx−3y+z的值．
- 已知实数x,y,z满足:xyz不等于0,2x+3y-13z=0,x-2y+4z=0,求(x^2+y^2-z^2)/(xy-yz+zx)
- 已知4x-y-2z=0,2x-3y+4z=0,且xyz不等于0
- (2x 1)(x 8)＝27
