Answer:
it is assumed that only A and B can be used, for the reason that in binary there are only two Variables.
Explanation:
In number bases digits include are from 0 to base-1, e.g. in base two (binary), we have from 0 to 2-1. that means we only have 0 and 1. there's no other digit or variable allowed apart from 0 and 1 in base 2 (binary). so in the binary message sending device, a message can only be sent as a sequence of states (A and B).

15x - 35 is equivalent
