    Ok, so since it doesn't give a value for "my age", we'll call it x. So the sentence translates into an equation ...

    200 reduced means ... 200 -

    by 2 times my age means ... 2x

    equals 16 means ... = 16

    200 - 2x = 16

    Now let's solve for x to find "my age"

    First subtract 200 from each side to begin to isolate x

    -2x = - 184

    Divide each side by - 2 to isolate x

    x = - 184/-2

    x = 92

    I'm 92 years old!
