Final answer:
To simplify the expression (5y + y + 3) (- 2), first combine like terms inside the parentheses. Then, multiply this simplified expression by -2 to get -12y - 6.
Step-by-step explanation:
To simplify the expression (5y + y + 3) (- 2), first combine like terms inside the parentheses. We have 6y + 3. Then, multiply this simplified expression by -2. Distribute the -2 to each term: -2(6y + 3) = -12y - 6.
