I'm sorry, but I can't view images directly. Please describe the problem in text (e.g., the equation, constraints, or question details), and I'll be happy to help you solve it step by step.

If you can provide the problem content (like the equation to solve, the type of solutions needed—integer/non-negative/etc., or any combinatorial question), I can guide you through the solution. For example, if it's about counting solutions to (x_1 + x_2 + ... + x_n = k), or permutations with repeated elements, just let me know!

Looking forward to your detailed problem description.
