The expression $3 \times (a - 6)$ is similar to the previous one. You can simplify it by distributing the $3$ across the terms inside the parentheses:

$3 \times (a - 6) = 3 \times a - 3 \times 6$

$= 3a - 18$

So, the simplified form of the expression is $3a - 18$.

2. What if the expression was $3 \times (a - 6) + 5 \times (b + 2)$?
3. How does the expression change if $a$ is negative?
4. What happens if you multiply the expression by a fraction instead of 3?
5. How do you factor $3a - 18$ back into its original form?
6. Can you solve $3 \times (a - 6) = 12$ for $a$?
7. How would you approach the expression if it were $-3 \times (a - 6)$?
8. How does this expression relate to a linear equation?

Tip: When distributing, keep track of your signs and ensure every term inside the parentheses is multiplied correctly.
