Final answer:
To find the total number of pages in both books combined, we add the number of pages in the first book with the number of pages in the second book.
Step-by-step explanation:
Let's denote the number of pages in the first book as x. Since the second book has 125 pages more than the first, we can express the number of pages in the second book as x + 125. To find the total number of pages in both books, we add the number of pages in the first book with the number of pages in the second book: x + (x + 125). Simplifying the expression, we get 2x + 125. Therefore, the total number of pages in both books combined is 2x + 125.
Since we are not given the specific value of x, we cannot calculate the exact total number of pages in both books combined. Therefore, we cannot confirm that the answer is 7290, 163, or 422.
