Answer 3

Problem Analysis

To solve this problem, we need to determine the initial number of books on the shelf. We are given that after removing 8 books from the shelf and adding 17 books back, the total number of books on the shelf became 22. Let's assume the initial number of books on the shelf is represented by the variable 'x'. We can set up the equation as follows:

x - 8 + 17 = 22

Solving the Equation

To solve the equation, we will simplify and isolate the variable 'x' on one side of the equation.

x - 8 + 17 = 22 x + 9 = 22

Next, we will isolate the variable 'x' by subtracting 9 from both sides of the equation.

x + 9 - 9 = 22 - 9 x = 13

Answer

The initial number of books on the shelf was 13.
