.
Let x be the number of newspapers John delivers in a day (the value under the question).


Then Bob delivers (x-9) newspapers.


The condition says


    7*(x + (x-9)) = 861.


Simplify and solve for x :


    7x + 7x - 63 = 861

    14x = 861 + 63

    14x = 924

     x  = 924%2F14 = 66.


ANSWER.  John delivers 66 newspapers per day.
