Come on!! It is really not difficult to make a diagram. Takes about 5 seconds.
As it is, I cannot help. It seems to be you have a black king on e7. And then you say, white as ke7, Ne4. So the white king is also on e7!! It's not a forced win; it's an illegal position.
Very annoying. If you could have at least been careful to say where the pieces were I would have created the diagram for you.
The king + rook can overcome the blockade of the king and knight, so the pawn will keep moving forward.
Also black can play rook takes knight any time the pawn endgame is winning.
These are the basic ideas, yes it's a win.
