Let's solve the problem step by step:

Let the two numbers be 'x' and 'y'.

Given information:

  • The sum of the two numbers is 25: x + y = 25.
  • The difference between them is 15: x - y = 15.

We can form two equations based on the given information:

Equation 1: x + y = 25 Equation 2: x - y = 15

To solve the system of equations, we can add Equation 1 and Equation 2:

(x + y) + (x - y) = 25 + 15

Simplifying the equation, we get:

2x = 40

Divide both sides of the equation by 2:

x = 40 / 2

Simplify:

x = 20

Substitute the value of x into Equation 1 to find the value of y:

20 + y = 25

Subtract 20 from both sides of the equation:

y = 25 - 20

Simplify:

y = 5

Therefore, the two numbers are 20 and 5.
