x/7 = A 6/7 = (7 A + 6)/7
x/6 = B 5/6 = (6 B + 5)/6
so x = 7 A + 6
and x= 6 B + 5
7 A +6 = 6 B + 5
6 B - 7 A = 1
what multiples of 7 and 6 differe by one?
35 and 36 or 48 and 49 ?
try 35 and 36
A = 5 and B = 6
x = 6 B + 5 = 41
or
x = 7 A + 6 = 41 sure enough
x/6 = B 5/6 = (6 B + 5)/6
so x = 7 A + 6
and x= 6 B + 5
7 A +6 = 6 B + 5
6 B - 7 A = 1
