{-y-3(-3y+5)
To simplify the expression, we can start by removing the parentheses:
-y - 3(-3y + 5)
Distribute the negative sign to each term inside the parentheses:
-y - 3(-3y) - 3(5)
Simplify the doubled negatives:
-y + 9y - 15
Combine like terms:
(9y - y) - 15
Simplify further:
8y - 15
So the simplified expression is 8y - 15.
