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%281%2C3%2C+%282+%2B+N%29%2F%287+-+2N%29%2C+%22=%22%2C+5%29

I believe you now have what you need to solve for N, the number being sought!
