1. The problem asks how to solve the last question, but since no specific question is provided, I will explain how to approach solving a typical algebra problem step-by-step. 2. First, identify what the problem is asking for and write down the given information. 3. Use relevant formulas or equations related to the problem. For example, if it is an equation to solve, write it clearly. 4. Perform algebraic operations step-by-step, such as expanding, factoring, combining like terms, and isolating the variable. 5. When dividing both sides by a common factor, show the cancellation explicitly using \cancel{} notation in LaTeX. 6. Simplify the expression fully to find the solution. 7. Check your answer by substituting it back into the original equation if possible. Since the exact last question is not provided, this general approach will help you solve most algebra problems.
