The larger of two whole numbers is five times the smaller. If the larger number is increased by 3, it equals 15 more than the smaller. Find both numbers.

Question

Solve this problem, I don;t know how to do it.

Answer 1

l = 5s

l + 3 = s + 15

 

5s - 3 = s + 15

4s = 12

s = 3

 

l = 5s = 5(3) = 15
