Question 10: Neo and Thabo's ages

  1. Define variables for current ages.

    Let Neo's current age be NN and Thabo's current age be TT.

  2. Formulate equations based on the given information.

    "Neo is now three times as old as Thabo":

    N=3T(1)N = 3T \quad (1)

    "Two years ago she was four times as old as Thabo then":
    Neo's age two years ago was N−2N-2.
    Thabo's age two years ago was T−2T-2.

    (N−2)=4(T−2)(2)(N-2) = 4(T-2) \quad (2)
