Question

for the relation (2 x) of base 9=(3y) of base 7 the possible values of x and y are

Answer 1

So,

This is a question from number systems

Now,

We expand the bracket,

9× 2 + x = 7×3 + y

x-y = 3

Now,

x<9 and y <7

So,

The integer solutions possible are,

(3,0) (4,1) (5,2) (6,3) (7,4) (8,5)

These are the possible solutions

Hope this helps !!!!!!!!!!
