x+y+z=88,1500x+800y+500z=95000x+y+z=88,1500x+800y+500z=95000x+y+z=88,1500x+800y+500z=95000三元方程组如果不够三
x+y+z=88,1500x+800y+500z=95000
x+y+z=88,1500x+800y+500z=95000
x+y+z=88,1500x+800y+500z=95000
三元方程组如果不够三个方程的话可以有无数组解.求正整数解可用以下方法：
x+y+z=88 5x+5y+5z=440
1500x+800y+500z=95000 15x+8y+5z=950
10x+3y=510 令y=10a则10x+30a=510
x+3a=51
x=51-3a=3(17-a)
z=88-x-y=88-51+3a-10a=37-7a
x>0 3(17-a)>0 17-a>0 a0 10a>0 a>0
z>0 37-7a>0 37>7a a
x+y+z=88,1500x+800y+500z=95000
(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
z+=x>y?++x:
x=y; y=z; z=x/y
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+z+u)=y/(z+u+x)=z/(u+y+x)=u(x+y+z)求(x+y)/(z+u)+(y+z)/(y+x)+(z+y)/(x+y)+(u+x)/(z+y)
已知(x+y)(x+z)=x,(y+z)(y+x)=2y,(z+x)(z+y)=3z,求x,y,z
fangchengzu:X+Z=Y 7Z=X+Y+Z X+Y+Z=14
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
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
