x除以2=y除以3=z除以5 2x+y+3z=88 求x = y = z=
x除以2=y除以3=z除以5 2x+y+3z=88 求x = y = z=
x除以2=y除以3=z除以5 2x+y+3z=88 求x = y = z=
x=8,y=12,z=20 很简单啊!不懂问我
1除以x+2除以y+3除以z=5,3除以x+2除以y+1除以z=7,则求(1除以x+1除以y+1除以z)的值
已知x除以2=y除以3=z除以4,且x≠0,求x+y+z除以x-2y+3z的值,
x除以2=y除以3=z除以5 2x+y+3z=88 求x = y = z=
x除以2=y除以3=z除以5 2x+y+3z=88 求x = y = z=
已知x除以2=y除以3=z除以-7≠0
(x+y)除以2=(y+z)除以3=(z+y)除以4,x+y+z=27这个方程怎么解啊.
已知(x+y)除以2=(y+z)除以3=(x+z)除以4,且2x+4y+6z=100,则xyz分别是多少?
已知X除以3等于Y除以4等于Z除以5,求X加Y除以X减2Y加3Z
若x除以10=y除以8=z除以9,则x+y+z除以y+z
X除以Y=Y除以Z=3分之2 2X+3Y-=17 三元一次的
若x+y除以3=y+z除以5=z+x除以4,且xyz≠0,则x:y:z=?
已知y,z为质数,(1除以x)+(1除以y)=(z除以3),且x=yz,求2008x+5y+3z.
已知x+2y-3z=0,2x+3y+5z=0,求(x+y+z)除以(x-y+z)
已知x+2y-3z=0,2x+3y+5z=0,求(x+y+z)除以(x-y+z)
已知2x+3y-4z=0,3x+4y+5z=0,求x+y+z/(除以)x-y+z的值.
已知2x+3y-4z=0,3x+4y-5z=0.求x+y+z除以x-y+z,
已知x+2y-3x=0,2x+3y+5z=o.求x+y+z除以x-y+z
x除以Y+Z=Y除以Z+X=Z除以Y+x=K K 等于
