Problema Solution
Donna is 12 years younger than her brother. In 2 year, she will be 14 years more than more than half as her brother? how old is each?
Answer provided by our tutors
let
d = the age of Donna
b = the age if her brother
Donna is 12 years younger than her brother
d = b - 12
in 2 year, she will be 14 years more than more than half as her brother
d + 2 = 14 + (b + 2)/2
by solving the system of equations
d = b - 12
d + 2 = 14 + (b + 2)/2
we find
d = 38 years
b = 50 years
