Calculating the Total Number of Books on Two Shelves

To calculate the total number of books on the two shelves, we can use the information provided.

Let's denote the number of books on the first shelf as x and the number of books on the second shelf as x + 7.

According to the information provided, the number of books on the first shelf is 15, and the number of books on the second shelf is 7 more than the first shelf.

So, we can set up the equation: x + (x + 7) = Total number of books on both shelves

Now, we can solve for the total number of books on both shelves.

Solution

x + (x + 7) = 15 + (15 + 7) 2x + 7 = 37 2x = 37 - 7 2x = 30 x = 15

So, the number of books on the first shelf is 15, and the number of books on the second shelf is 15 + 7 = 22.

Therefore, the total number of books on both shelves is 15 + 22 = 37.
