rose is twiceas old as luz if the age of rose is added to half of luz the result is 60 what were their age seven years ago
Answer provided by our tutors
let
r = the age of Rose
l = the age of Luz
rose is twiceas old as luz
r = 2l
if the age of rose is added to half of luz the result is 60
r + l/2 = 60
by solving the system of equations
r = 2l
r + l/2 = 60
we find
r = 48 years
l = 24 years
