求计算x/(x-y+z)+(2x+2z)/(y-x-z)-(y+z)/(y-x-z)的结果和过程
求计算x/(x-y+z)+(2x+2z)/(y-x-z)-(y+z)/(y-x-z)的结果和过程
求计算x/(x-y+z)+(2x+2z)/(y-x-z)-(y+z)/(y-x-z)的结果和过程
x/(x-y+z)+(2x+2z)/(y-x-z)-(y+z)/(y-x-z)
＝x/(x-y+z)-(2x+2z)/(x-y+z)+(y+z)/(x-y+z)
=(x-2x-2z+y+z)/(x-y+z)
=(-x+y-z)/(x-y+z)
=-1
计算:x^2/(x-y)(x-z)+y^2/(y-x)(y-z)+z^2/(z-x)(z-y)
计算:(y-x)(z-x)/(x-2y+z)(x+y-2z)+(z-y)(x-y)/(x+y-2z)(y+z-2x)+(x-z)(y-z)/(y+z-2x)(x-2y+z)
计算（x-y-z)^2
求计算x/(x-y+z)+(2x+2z)/(y-x-z)-(y+z)/(y-x-z)的结果和过程
计算(2x+y+z)(2x-y-z),
计算(x+2y-z)(2y+z-x)
计算(x-2y+z)(z-x-2y),
(x一2y+z)(-x+2y+z)(计算)
计算:(x+2y-z)(x-2y-z)
计算(x+2y-z)(2y+z-x)
计算：(x-y-z)^2-(x-y+z)^2
(x+2y-z)(x-2y-z)计算过程
计算：(x+2y-z)(x-2y+z)
2(x+y-z)-3(x-y+z)-5(x+y-z)+6(x-y+z) 计算
已知：x^2/(z+y)+y^2/(x+z)+z^2/(x+y)=0,求x/(z+y)+y/(x+z)+z/(x+y)的值.
x^2/(z+y)+y^2/(x+z)+z^2/(x+y)=0,求x/(z+y)+y/(x+z)+z/(x+y)的值
已知(x+y)(x+z)=x,(y+z)(y+x)=2y,(z+x)(z+y)=3z,求x,y,z
