Let's set these two numbers as 'a' and 'b'
Now, let's set up equations based on the information known:
- the sum of the two numbers is 52 --> a + b = 52
- the difference is 28 --> a - b =28
Equations
- a + b = 52 -- equation 1
- a - b = 28 -- equation 2
Solve:
(Equation 1) + (Equation 2)
2a = 80
a = 40 -- equation 3
(Equation 3)
40 + b = 52
b = 12
So a = 40 and b = 12
Hope that helps!
