Answer: - 27y + 16z
Explanation:
The given expression is
-3y - 4(-5z + 6y) - 4z
The first step is to expand the parentheses by multiplying the terms inside with the term outside. We have
- 3y - 4 * - 5z + - 4 * 6y - 4z
- 3y + 20z - 24y - 4z
By collecting like terms, we have
- 3y - 24y + 20z - 4z
- 27y + 16z
