    400 reduced by 3 times my age is 214

    Let my age be a. We have:

    3 times my age:
    3a

    400 reduced by 3 times my age:
    400 - 3a

    The word is means an equation. So we set 400 - 3a equal to 214
    400 - 3a = 214

    Now if you want to solve this equation for a, we type it in the search engine and we get;
    a = 62
