You can put this solution on YOUR website! Let n = the number
Twice a number decreased by three = 2n - 3.
...that difference divided by five more than the number = (2n - 3)/(n + 5).
The entire statement = (2n - 3)/(n + 5).
What exactly do you need done with this algebraic fraction?
In other words, where is the rest of the question?
