Final answer:
To simplify the expression, distribute 5, combine like terms, and evaluate constant terms.
Step-by-step explanation:
To simplify the given expression 5(2y + 4) + (5y - 3), we apply the distributive property. Multiplying 5 to each term inside the parentheses, we get 10y + 20. Then, we combine like terms by adding 10y and 5y, resulting in 15y. Finally, combining the constant terms 20 and -3, we have 17. Therefore, the simplified expression is 15y + 17.
