1/4N = 20
N = (20)(4) = 80

First, subtract 5 from both sides
1/4N = 25-5, or
1/4N = 20
Then multiply both sides by 4 to get N alone
N = 20*4 = 80

Assume that question is:-
(1/4).N + 5 = 25
N + 20 = 100
N = 80
Please note that the way you have written the question it could mean:-
1/(4N) + 5 = 25 which is a completely different question.
The moral behind the story is to use brackets so that there is no misunderstanding.
