Step-by-step explanation:

Step 1: Define

4y - y(3 - 7y) + 5 + 2(8 - y)

Step 2: Simplify

1. [Distributive Property] Distribute parenthesis:                                               4y - 3y + 7y² + 5 + 16 - 2y
2. Combine like terms (y):                                                                                    7y² - y + 5 + 16
3. Combine like terms:                                                                                         7y² - y + 21
