      @lalithasrip asked : “what is the value of P if the equation are consistent and x not equal to 0 and not equal to Y ???”

      The equations are

      5x+4y=32
      2py+15x=96

        multiply 1st eq by 3
        so it becomes 15x + 12y = 96
        and 2nd eq is 15x + 2py = 96
        subtract both
        u will get 2py = 12
        2p = 12
        p = 6
