已知x+y=1,xy=1/5,则x^2y=xy^2已知x+y=1,xy=1/5,则x^2y=xy^2已知x+y=1,xy=1/5,则x^2y=xy^2x^2y+xy^2=xy(x+y)=1/5x^2y
已知x+y=1,xy=1/5,则x^2y=xy^2
已知x+y=1,xy=1/5,则x^2y=xy^2
已知x+y=1,xy=1/5,则x^2y=xy^2
x^2y+xy^2 =xy(x+y)=1/5
x^2y=xy^2化简得x=y,即解出x=y就行。x+y=1,xy=1/5解方程组可得x=y=一个数，就出来啦
已知xy/x+y=1/2,则代数式3x-5xy+3y/-x+3xy-y=
已知x+y=1,xy=1/5,则x^2y=xy^2
已知x+y=1,xy=-2,则x²y+xy²-2xy
已知x+y=-1,xy=-2,求代数式-5（x+y)+(x-y)+x(xy+y)的值
已知1/x=3+1/y,则(2x-5xy-2y)/(y+3xy-x)=_______.
已知1/x+1/y=5,则2x-5xy+2y/x+2xy+y
已知1/x+1/y=5,则2x-5xy+2y/x+2xy+y详解
已知1/x-1/y=-3,则x+5xy-y/3x-2xy-3y=
已知1/x-1/y=5,则2x+3xy-2y/y+2xy-x
已知2/X-1/Y=3,则(X-2Y-XY)/(5XY+6Y-3X)=?
已知2/x-1/y=3,则(2y-x+4xy)/(3x-6y-5xy)=?
已知1/X-1/Y=5 ,则x-2xy-y/4x+3xy-4y
已知x+y=-1,xy=-2,求代数式-5（x+y)+(x-y)+2(xy+y)的值
1 已知1/X+1/Y=1/X+Y 则 Y/X+X/Y=2 已知1/X-1/Y=5,则3X+5XY-3Y/X-3XY-Y=
已知x/1-y/1=3,则5x+xy-5y/x+2y-y的值为
已知1/x-1/y=3,则5x+3y-5y/x-2xy-y的值
已知x+y=1,x>0,y>0,则2x+y/xy等于
已知1/x=1/y=6,则3x-2xy+3y/3xy+x+y=?已知1/x+1/y=6,则3x-2xy+3y/3xy+x+y=?
