If $n = m + x$ then $m = n - x$.

3. ## reply to prove it

If I had known how to work a problem I would not have come on this forum to ask how it was done. I do not appreciate being called stupid. The only stupid question is one that is not asked.

No-one has called you stupid.

You asked to know what m is. The only way you can find a value of m is if you're given values of n and x.

And once you have the values of n and x, then you work out m as I have described.

Don't be so rude.
