What two numbers were added if the sum is more than one of them by 26 and more than the other by 9? Find the amount.

let one number x, and the second y, then their sum (x + y).
Then, by the condition of the problem, the sum is more than one of them by 26, we have (x + y) – x = 26, hence y = 26
And the second condition of the sum is more than the second number by 9, then (x + y) – y = 9, hence x = 9
We have an answer to the problem. The first number is 9 and the second is 26
