Problema Solution

the difference of two numbers is 100.8 and the larger number is 3 times the smaller number. Find the sum of the two numbers.

Answer provided by our tutors

let 'x' and 'y' represent the two numbers, and let x > y


the difference of two numbers is 100.8:


x - y = 100.8


the larger number is 3 times the smaller number:


x = 3y


by solving the system of equations:


x - y = 100.8


x = 3y


we find:


x = 151.2


y = 50.4
