finding the values of unknown coefficents x,y

hello,

           A is a matrix     1  2   3 

                             3  4   5 

                                                                                     X  is a matrix         x

                             y 

      B is a matrix     0

                        0                       

    AX=B ; X= INV A B

Trivial. x = 0 and y = 0
