    So if Zoe added 7 more pencils then all you have to do is just do the opposite

    being the equation stated

    X+7=24

    X being the number of pencils before added

    To find the answer just do the opposite

    24-7=X

    and X=17

    This problem can be solved using subtraction. We want to know how many pencils were in the box before the 7 pencils were added, so we must subtract 7 from 24.

    24 - 7 = 17.

    There were 17 pencils in the box to start with.
