Today: 
m = 3w    (man's age is three times of that of the woman).

In 20 years after:
m + 20 = 2(w+20).

So you have the system of two equations in two unknowns:

m = 3w,              (1)
m + 20 = 2(w+20).    (2)

Substitute m = 3w from (1) to (2). You will get

3w + 20 = 2(w+20),   or  3w + 20 = 2w + 40,   or  w = 40-20 = 20.

Answer. Woman is 20 years now. The actor is 60 years now.

Thank you for submitting so fresh formulation of so traditional problem.
