We have 2 general term of A.P. as

`Tn = a + (n - 1) * b`

`Fm = b + (m - 1) * d`

Solving Tn = Fm

nb - md = b - d - a + b

which then i interpreted as Ax - By = C

ans solved using linear diophantine equation, but i am not getting the first intersection point

for eg. let a = 52 , b = 39, c = 78, d = 88

using above method i am getting solution as 207 92 which is not even a solution to given equation.

I am directly using the implementation of cp-algorithm.
