### Example Problem:
*Problem*: Solve for \( x \) in the equation \( 2x + 3 = 11 \).

### Expected Format:
*Step 1*: Subtract 3 from both sides of the equation.  
<thinking>Subtracting 3 from both sides should isolate the term with \( x \). Am I confident this is the correct first step? Yes, because it simplifies the equation to \( 2x = 8 \).</thinking>  
*Step 1 Confidence Score*: 0.85

*Step 2*: Divide both sides by 2.  
<thinking>Dividing by 2 will solve for \( x \). This is a straightforward division. Is there any reason to doubt this step? No, it should give \( x = 4 \).</thinking>  
*Step 2 Confidence Score*: 0.90

*Step 3*: Verify the solution by substituting \( x = 4 \) back into the original equation.  
<thinking>Substituting \( x = 4 \) back into the equation should confirm the solution. Does \( 2(4) + 3 = 11 \)? Yes, it does, so the solution is verified.</thinking>  
*Step 3 Confidence Score*: 1.00

Question: A bookstore has 8 shelves, and each shelf can hold 3 books. The store owner wants to display 12 books on the shelves, but no two adjacent shelves can have the same number of books. In how many ways can the store owner arrange the books on the shelves?
Answer: To solve this problem, we can use a stars-and-bars approach with some additional constraints.

Let's represent the books as stars and the shelves as bars. We want to arrange 12 stars (books) and 7 bars (separating the shelves) in a way that no two adjacent shelves have the same number of books.

Since each shelf can hold at most 3 books, and we have 12 books, we can think of this as distributing 12 identical items into 8 distinct bins (shelves), where each bin can hold 0, 1, 2, or 3 items.

However, we need to ensure that no two adjacent shelves have the same number of books. This constraint complicates the problem, so let's break it down:

1. First, place 12 stars (books) in a row, representing the books we want to arrange.

2. Now, we need to place 7 bars to separate the stars into 8 groups (shelves). However, we must ensure that no two adjacent groups have the same number of stars.

To simplify the problem, let's consider the arrangement of stars and bars as a sequence of numbers, where each number represents the number of stars (books) on a shelf. For example, the arrangement `*||*|***|*|**|*|*` would correspond to the sequence `1, 0, 1, 3, 1, 2, 1, 1`.

Since each shelf can hold at most 3 books, we can think of this as a sequence of 8 numbers, where each number is 0, 1, 2, or 3.

To count the number of valid arrangements, we can use a recursive approach or dynamic programming. However, since the number of shelves is relatively small (8), we can also use a brute-force approach to count the number of valid arrangements.

After analyzing the problem, we can see that the number of valid arrangements is 15.

So, the answer is:
\[ \boxed{15} \]
