X+Y+Z=651 Y=110%Z X=105%Y
X+Y+Z=651 Y=110%Z X=105%Y
X+Y+Z=651 Y=110%Z X=105%Y
X+Y+Z=651
Y=110%Z
X=105%Y
设 x y z分别为 115.5 k 110k 100k
115.5 k + 110k + 100k = 325.5 k = 651
k =2
x y z分别为 231 ,220 ,200
把y=1.1z,x=1.05y=(1.05乘1.1)z,就能求出z,y和x就出来了
(x+y-z)(x-y+z)=
X+Y+Z=?
x/y=(x+z)/(y+z)y/z=(x+y)/(x+z)
已知 x/(y+z)+y/(z+x)+z/(x+y)=1求 (x*x)/(y+z)+(y*y)/(x+z)+(z*z)/(x+y)=?
(y+z)/x=(z+x)/y=(x+y)/z求x+y-z/x+y+z的值
fangchengzu:X+Z=Y 7Z=X+Y+Z X+Y+Z=14
z+=x>y?++x:
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?
x=y; y=z; z=x/y
(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)
X+Y+Z=651 Y=110%Z X=105%Y
z=x^(y/z) 偏导数
已知(x+y)(x+z)=x,(y+z)(y+x)=2y,(z+x)(z+y)=3z,求x,y,z
若z分之x+y+z=y分之x-y+z=x分之-x+y+z,求xyz分之(x+y)(y+z)(z+x)
已知 (x+y-z)/z=(x-y+z)/y=(y+z-x)/x,且xyz≠0,求代数式 ((x+y)(y+z)(x+z))/xyz
x分之y+z=y分之z+x=z分之x+y(x+y+z不等于0),求x+y+z分之x+y-z
分式加减法:已知x+y/z=x+z/y=y+z/x(x+y+z≠0),求x+y-z/x+y+z
已知x+y/z=x+z/y=y+z/x(x+y+z≠0),求x+y-z/x+y+z的步骤
