<pre>A lot of these problems are posted and seem to be from the same person. I don't know what kind of problem you're having,
but let me help you set up the equation, after which you should be able to find the solution.

Let the number be N
Then we get: {{{matrix(1,3, (2 + N)/(7 - 2N), "=", 5)}}}
I believe you now have what you need to solve for N, the number being sought!
