已知X-XY-2Y=0求2X+3XY-Y/X-2XY+5Y
若x+y-5xy=0,求(2x-3xy+2y)/(x+2xy+y)的值
3xy-( )=5xy-2 x-(5x-3y)+( )=-2x+2y
已知xy/x+y=3,求代数式2x-5xy+2y/x-3xy+y
已知xy/x+y=2,求代数式3x-5xy+3y/-x+2xy-y的值
已知Y-x=3xy,求(5x+3xy-5y)÷(x-2xy-y)
已知x+y分之xy=2,那么3x-5xy+3y分之3xy-x-y=
若xy/x+y=2,则3x-5xy+3y/-x+3xy-y=?/是分之
xy/x+y=2 求3x-5xy+3y/-x+3xy-y的值?
