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

x + y = 151.2 + 50.4 = 201.6
the sum of the two numbers is 201.6.
