Problema Solution
The sum of two integers is 7 and the sum of their squares is 25.
Answer provided by our tutors
Let 'x' and 'y' represent the integers.
The sum of x and y is 7:
x + y = 7
y = 7 - x
The sum of x^2 and y^2 is 25:
x^2 + y^2 = 25
Plug y = 7 - x into the above equation:
x^2 + (7 - x)^2 = 25

x1 = 4
x2 = 3
For x = 4 we have y = 7 - 4 = 3.
For x = 3 we have y = 7 - 3 = 4.
The two integers are 3 and 4.
