Based on the info u have given, i just guessing that its 7.2
I'm probably wrong though
5 + n = 17 that is what the equation would look like but if you wish to solve for the variable n then you would subtract 17 - 5 = 12, so that is the answer so tecnically I just gave you the answer to 2 questions please let me know if it helps.
