Problema Solution
The sum of two numbers is 15. When one of these numbers is added to three times the other, the result is 27. What are the numbers?
Answer provided by our tutors
let 'n' represent one number, then '15-n' represents the other and we have:
27 = n + 3(15-n)
solving for 'n' we have n=9
15-9 = 6
the numbers are 6 and 9
