    Answer:

    y-x=22

    Step-by-step explanation:

    If Alice had started at zero, and she measured her belt to be 22 inches long

    End Point- start point= 22

    22-0=22

    Let x be the starting point of measurement

    Let y be the ending point of measurement

    It means therefore that: y-x=22

    Her two points will be values of x and y that satisfies the equality

    y-x=22.

    E.g. If y=28, x=6

    28-6=22. These are possible endpoints.

    However, if y=27, x=6

    y-x=27-6=21

    These are not possible endpoints.
