What we’re looking for is the
value of k that will satisfy the equation.
The solution would be like this
for this specific problem:
5k =1 (mod
26)
Check how 5*5
= 25 = -1 (mod 26)
In this way,
5*(-5) = -5*5 = -25 = -(-1) = 1 (mod 26)
Thus, k = -5
= 21 (mod 26)
And 5^-1 =
21 (mod 26)
I am hoping that this answer has
satisfied your query and it will be able to help you in your endeavor, and if
you would like, feel free to ask another question.
