What are the two number have a sum of 14 and the difference of 4?

The sum of the sum and difference gives twice the larger number 14 + 4 = 18 → the larger number is 18 ÷ 2 = 9 The difference of the sum and the difference gives twice the smaller number 14 - 4 = 10 → the smaller number is 10 ÷ 2 = 5 → The two numbers are 9 and 5.

What are the steps in getting the product sum and difference of two terms?

Which two numbers sum to 81 and their difference is 25?

If their difference is 25 then the larger number is the smaller number plus 25. Let the smaller number be x then the larger number is x + 25 → their sum is x + (x + 25) = 81 → 2x = 56 → x = 28 → the two numbers are 28 and 53.
