Finding Two Numbers Given Sum and Difference

To find two numbers given their sum and difference, we can use the following formulas: 1. Let's denote the two numbers as x and y. 2. The sum of the two numbers is given by C and the difference is given by D. 3. The difference of the two numbers is given by X and the sum is given by Y.

Using these formulas, we can calculate the values of x and y.

Calculation

Let's denote the sum of the two numbers as C and the difference as D. Then, the two numbers can be calculated using the following formulas: 1. The first number x is given by: (C + D) / 2. 2. The second number y is given by: (C - D) / 2.

Result

Using the above formulas, we can calculate the values of x and y: 1. The first number x is 8. 2. The second number y is 2.

Therefore, the two numbers are 8 and 2.
