    In 16 years, Ben will be 3 times as old as he is right now.

    Let Ben's age right now be b.

    We have, in 16 years, Ben's age will be 3 times what his age is now:
    b + 16 = 3b

    Subtract b from each side:
    2b = 16

    Divide each side by 2
    b = 8

    Check our work:
    16 years from now, Ben's age is 8 + 16 = 24
    And, 8 x 3 = 24
