What is the answer to page 3.5 in punchline algebra book A?

In order to determine the answer to a specific page and question in a textbook like Punchline Algebra Book A, you would need to provide the specific question or problem presented on page 3.5. Without the exact question or context, it is impossible to provide a definitive answer. I recommend reviewing the question on page 3.5 and working through the problem using algebraic principles to arrive at the correct solution.
