    Max is 23 years younger than his father.Together their ages add up to 81.

    Let Max's age be m, and his fathers' age be f. We're given:
    1. m = f - 23 <-- younger means less
    2. m + f = 81
    Substitute Equation (1) into (2):
    (f - 23) + f = 81

    Combine like terms to form the equation below:
    2f - 23 = 81

    Typing this equation into our search engine, we get:
    f = 52

    Substitute this into Equation (1):
    m = 52 - 23
    m = 29
