Problema Solution
The difference between two numbers is five. The sum of the squares of the numbers is 157. What are the numbers?
Answer provided by our tutors
let 'x' and 'y' represent the numbers and x>y
The difference between two numbers is five:
x - y = 5
x = 5 + y
The sum of the squares of the numbers is 157:
x^2 + y^2 = 157
plug x = 5 +y into the last equation:
(5 + y)^2 + y^2 = 157
by solving we find:
y = 6

x = 5 + 6
x = 11
the numbers are 11 and 6.
