Write $N=x+x+1$ find $x$. Hint: it's not always possible, especially for even numbers. – Vasili Feb 05 '20 at 14:32

1Please try to make the titles of your questions more informative. For example, Why does $a<b$ imply $a+c<b+c$? is much more useful for other users than A question about inequality. From How can I ask a good question?: Make your title as descriptive as possible. In many cases one can actually phrase the title as the question, at least in such a way so as to be comprehensible to an expert reader.
