1. We need to clarify the context before explaining step 5 further, as "stap 5" means "step 5" in Dutch, but the previous steps or problem have not been provided. 2. Please provide the full problem or previous steps leading to step 5 so I can explain it thoroughly. 3. Once you provide the context or the math problem, I will break down step 5 in detail using clear explanations and LaTeX formatted math if needed.
