Marion is 4 years older than Pam. The sum of their years is 32 years. How old are Marion and Pam?
Answer provided by our tutors
let
m = the age of Marion
p = the age of Pam
Marion is 4 years older than Pam:
m = p + 4
The sum of their years is 32 years:
m + p = 32
by solving the system of equations
m = p + 4
m + p = 32
we find
m = 18 years
p = 14 years
