x;y;z=2;3;4,2x+y+z=22x;y;z=2;3;4,2x+y+z=22x;y;z=2;3;4,2x+y+z=22x:y=2:3得:y=(3/2)xx:z=2:4得:z=2x又因:2x+y
x;y;z=2;3;4,2x+y+z=22
x;y;z=2;3;4,2x+y+z=22
x;y;z=2;3;4,2x+y+z=22
x:y=2:3得:
y=(3/2)x
x:z=2:4得:
z=2x
又因:2x+y+z=22
即2x+(3/2)x+2x=22
所以 x=4
y=6 z=8
证毕.
【〇贰〇壹〇】
x+2y=3x+2z=4y+z 求x:y:z
x+y/2=z+x/3=y+z/4 x+y+z=27
试证明(x+y-2z)+(y+z-2x)+(z+x-2y)=3(x+y-2z)(y+z-2x)(z+x-2y)
已知(x+y)(x+z)=x,(y+z)(y+x)=2y,(z+x)(z+y)=3z,求x,y,z
2x+z=10 x+y-z=4 3x-y-z=0
x=y/z=z/3,x+y+z =12,求2x+3y+4z是多少,
(4x-2y-z)-{5x-[8y-2z-(x-2y)]-x-(3y-10z)}=?
证明 :x/(y+z)+y/(z+x)+z/(x+y)>=3/2其中 x,y,z>0
x/2=y/3=z/5 x+3y-z/x-3y+z
若x+y+z=3y=2z,则x/x+y+z=?
若x,y,z成等差数列,则(z-x)^2-4(x-y)(y-z)=
(x*x+2)(y*y+4)(z*z+8)=64xyz,求x,y,z
3x-y+z=4,2z+3y-z=12,x+y+z=6的解
x/2=y/3=z/4,则x+2y-z/z=?
设|x|-|y|+|z|=|x+y+z|,且|x+y|=4,|y+z|=5,|y|=3,求(x-y-z)^2的值
用行列式的性质证明:y+z z+x x+y x y z x+y y+z z+x =2 z x y z+x x+y y+z y z x 这个怎么证?
(4x-2y-z)-{5x-[8y-2z-(x+y)]-2(3y-10z)}=?好难啊
(x-2y+z)(x+y-2z)分之(y-x)(z-x) + (x+y-2z)(y+z-2x)分之(z-y)(x-y) + (y+z-2z)(x-2y+z)分之(x-z)(y-z)=?第三部分那个是 (y+z-2x)(x-2y+z)分之(x-z)(y-z)
