Cary is 9 years older than Dan. In 7 years, the sum of their ages will equal 93.
Find both of their ages now.
Answer provided by our tutors
let
c = the current age of Cary
d = the current age of Dan
Cary is 9 years older than Dan:
c = d + 9
In 7 years, the sum of their ages will equal 93:
c + 7 + d + 7 = 93
by solving the system of equations
c = d + 9
c + 7 + d + 7 = 93
we find
c = 44 years
d = 35 years
