Question

Find an expression which represents the difference when (4x – 2y) is subtracted

Answer 1

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
