1.   2xy/(x+y)=3/2                 xy/(2x-y)=-3/10

    4xy=3x+3y                      10xy=-6x+3y............(2)

    y(4x-3)=3x                       put (1) into (2),  10x[3x/(4x-3)]=-6x+3[3x/(4x-3)]        

    y=3x/(4x-3)...........(1)                                    30x^2/(4x-3)=-6x+9x/(4x-3)

                                                                       10x/(4x-3)=-2+3/(4x-3)

                                                                       10x=-2(4x-3)+3

         y=3x/(4x-3)                                            10x=-8x+6+3

             y=3(1/2)/[4(1/2)-3]                           18x=9

               =3/2/(2-3)                                        x=1/2

              =3/-2

             =-3/2                          so x=1/2, y=-3/2


psushil2003: I'm not sure with this answer
marco417chan: whats the model answer
psushil2003: ok this is what i got 1,-3
marco417chan: um, i will try twice
marco417chan: i think it should be y=-3/2 , x=1/2
psushil2003: ok thanks
psushil2003: anyone have an answer pls
psushil2003: surely i'll mark brainliest.......
