Question 98801

    x+y=2
y=4x+7


      x+y = 2............(1)

    -4x+y = 7...........(2)

   subtracting (1)  &(2)   we get 5x = -5  or   x = -1

     substituting for x in (1) we get -1+y = 2

                                        y = 2+1 = 3

       the values of x and y are -1 and 3 respectively.
