### 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: Let $x$, $y$, and $z$ be positive integers such that $2x+7y+3z=100$. What is the greatest possible value of $xyz$?
Answer: We can use the AM-GM inequality to find the maximum possible value of $xyz$.

The AM-GM inequality states that the arithmetic mean of a set of non-negative numbers is greater than or equal to their geometric mean.

For positive real numbers $a_1, a_2, \ldots, a_n$, the inequality is:
\[ \frac{a_1 + a_2 + \cdots + a_n}{n} \geq \sqrt[n]{a_1 a_2 \cdots a_n} \]

Apply the AM-GM inequality to the numbers $2x$, $7y$, and $3z$:
\[ \frac{2x + 7y + 3z}{3} \geq \sqrt[3]{(2x)(7y)(3z)} \]

Given that $2x + 7y + 3z = 100$, substitute this into the inequality:
\[ \frac{100}{3} \geq \sqrt[3]{42xyz} \]

Rearrange the inequality to solve for $xyz$:
\[ 42xyz \leq \left( \frac{100}{3} \right)^3 \Rightarrow xyz \leq \frac{1}{42} \left( \frac{100}{3} \right)^3 \]

Simplify the right side:
\[ xyz \leq \frac{1}{42} \left( \frac{1000000}{27} \right) \]

\[ xyz \leq \frac{1000000}{1134} \approx 882.35 \]

Since $x$, $y$, and $z$ are positive integers, the greatest possible value of $xyz$ must be an integer less than or equal to $882.35$.

The greatest possible integer value for $xyz$ is $\boxed{882}$.
