初二数学分式:若X/2=Y/3=4/Z不等于0.求2X+3Y/z的值
若x/2=y/3=z/4不等于0,求x+y+z/x+y-z的值
已知X/2=y/3=z/4,试求x+y-z/x+y+z的值 (这是初二分式) 要过程
x y z 满足等式x/4=y/3=z/2不等于0,求分式x二次方+y二次方/xy-xz的值
已知x=y/3=z/5.且x+y-2z不等于0.求2x+3y-z/x+y-2z的值是多少
已知x/2=y/3=z/4,且x+y+z不等于0,求2x+3y-4z/x+y+z的值
已知4x-3y+z=0,x+2y-8z=0,xyz不等于0,求x+y-z/x-y+2z的值
已知x,y,z满足{4x-3y-3z=0,x-3y+z=0.(x不等于0,y不等于0,z不等于0)求x/z和y/z的值
试一试:已知X/3=Y/4=Z/6不等于0,求分式X+Y-Z/X-Y+Z的值
方程组:x-2y+4z=0,2x+3y-3z=0...xyz不等于0,求(2x+y-z)\(2x-y+z)
方程组{4x-3y-3z=0,x-3y+z=0,(x.y.z不等于0),求x/z和y/z的值?
4x-3y-3z=0 x-3y+z=0 并且X Y Z不等于0 求x:z 和y:z的值
