of their ages is 84. How old is the son?
Answer provided by our tutors
let
w = woman's age
s = her son's age
A woman’s age is three years more than twice her son’s age:
w = 3 + 2s
The sum of their ages is 84:
w + s = 84
by solving the system of equations:
w = 3 + 2s
w + s = 84
we find:
w = 57 years
s = 27 years
