Answer:
-3y
Step-by-step explanation:
"(4x – 2y) subtracted from (4x – 5y)"
(4x – 5y) - (4x – 2y) =
Drop the first set of parentheses since it is unnecessary.
= 4x – 5y - (4x – 2y)
Distribute the negative sign to the left of the parentheses by changing each sign inside the parentheses.
= 4x – 5y - 4x + 2y
Combine like terms.
= 4x - 4x - 5y + 2y
= 0 - 3y
= -3y
