    If Mitch wants to have 10 spare bars and he could only afford 28, how many candy bars his friends could have?

    Correct, now if you want to distribute equally the amount of candy among 'f' friend, how many candy bars will each friend get?

    We do not know how many friends he has, he has 'f' friends.

    but it says 2 to each friend so i did 18/2

    Yes, 9 friends, but each friend would get 2 bars, correct?

    But let's suppose we do not know and we do not want to solve the problem, we'll keep f as the number of friends, you agree that, 18/2 = f

    So in words, the amount of candy bars Mitch wants to keep for himself, added to the amount of candy bars his friends would get, gives 28

    Amount of candy bars Mitch wants to keep for himself is 10 Amount of candy bars his friend would get, in term of the variable 'f', would the the number of friend (f) times the number of candies each of them would receive, 2, thus, 2f Therefore the equation to express this would be?

    so which equation 2f-10=28?

    Partly correct, it's an adding operation, not a subtracting operation

    2f+10=28
