You could write it as a polynomial where a, b, and c are the roots (order doesn’t matter, as they are interchangeable):

(x-a)(x-b)(x-c)

Then, use Vieta’s formulas to find another expression for the sum of the triple pairs, double pairs, and single pairs.

Using that information, try to solve the system. This is a really cool problem!!!

The equation in the image is given as:

\[
abc + ab + bc + ca + a + b + c = 2024
\]

We are asked to find the sum of all possible values of \(c\), where \(a\), \(b\), and \(c\) are positive integers such that \(a < b < c\).

To approach this, the expression can be rewritten as:

\[
abc + ab + bc + ca + a + b + c = 2024
\]

This is a symmetric equation in \(a\), \(b\), and \(c\), meaning the variables can be swapped without changing the equation. However, since \(a < b < c\), we can focus on solutions with \(a < b < c\).

### Steps to solve:

1. **Trial and Error Strategy**: Since this is a Diophantine equation with positive integer solutions, we can manually substitute values for \(a\) and \(b\), solve for \(c\), and check which combinations satisfy the equation.

2. **Reduce and Factorize**: The equation resembles a polynomial form, but rewriting it directly using algebraic manipulation seems impractical because of the complex interactions between \(a\), \(b\), and \(c\). Therefore, a systematic search will help us determine the possible values of \(c\).

Let me proceed with this method to find the possible values of \(c\) and their sum.The possible values of \(c\) that satisfy the equation are \(26\), \(44\), and \(74\). The sum of all these different values of \(c\) is:

\[
26 + 44 + 74 = 144
\]

Would you like more details on how this was computed or explanations on any specific step?

Here are 5 related questions you might find helpful:

1. What are some alternative methods to solving this type of Diophantine equation?
2. How can we prove that there are no other possible values of \(c\)?
3. How would this problem change if we allowed non-integer solutions for \(a\), \(b\), and \(c\)?
4. What role do Vieta’s formulas play in simplifying symmetric polynomial equations?
5. How can constraints like \(a < b < c\) be exploited in mathematical problem-solving?

**Tip**: When solving Diophantine equations, simplifying the equation using common algebraic techniques or inequalities can often narrow down the search space for potential solutions!
