    Tanner: 15

    Lexy: 18

    Step-by-step explanation:

    Tanner's age: r

    Lexy's age: y

    r + y = 33

    r + 3 = y

    If you substitute y into the first equation, you get:

    r + r + 3 = 33

    2r = 30

    r = 15

    Tanner's age is 15 years old.

    Lexy's age is 15 + 3 = 18 years old.
