{x+y=8,y+z=10,x+z=6三元一次方程组如题,

解方程组：{x(x+y+z)=6 {y(x+y+z)=9 {z(x+y+z)=10 x+y=8 y+z=12 x+z=10 x+y+z= x+y=8 y+z=12 x+z=10 x+y+z= (x+y-z)(x-y+z)= 若X/10=Y/8=Z/9则X+Y+Z/Y+Z=? X/10=Y/8=Z/9,则X+Y+Z/2Y-3Z x+y=6,y+z=8,x+z=10求x、y、z的值 X+Y+Z=? x/y=(x+z)/(y+z)y/z=(x+y)/(x+z) (x+y+z)÷10=x+1.1 y+x=z-80+y-1 z-y=8x+y+8 x+z÷y=? 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)=? (4x-2y-z)-{5x-[8y-2z-(x-2y)]-x-(3y-10z)}=?
