1. The problem is to simplify the given expression or answer. 2. To simplify an expression, we combine like terms, factor where possible, and reduce fractions. 3. If the expression involves fractions, use the rule: $$\frac{a}{b} \div \frac{c}{d} = \frac{a}{b} \times \frac{d}{c}$$ and simplify by canceling common factors. 4. Show intermediate steps with canceled terms using \cancel{}. 5. Continue simplifying until no further reduction is possible. 6. The final simplified answer is the expression in its simplest form.
