    Teo is 11 years old and Richard is 26 years old.

    Step-by-step explanation:

    Let R be the age of Richard and T be the age of Teo.

    First set up the equations:

    The combined age of Teo and Richard is 37:

    R+T=37

    Richard is four years old than twice Teo's age:

    R=2T+4

    Then, solve the equations:

    Substitute (2) to (1) and solve for T:

    (2T+4) + T=37

    3T=11

    T=11

    Solve for R using (2):

    R=2 (11) + 4

    R=22+4

    R=26
