quick question. There is a question in the book saying "Every finite subset of a Hausdorff space is closed."

#### Explanation:
We begin with $5 a - 20$. The first thing I noticed with this problem is that both $5$ and $20$ are divisible by $5$. That means that we can factor out a $5$ from both components, which leaves us with $5 \left(a - 4\right)$.
