Question

I need help on finding out this answer i am really confused so plz help me

Answer 1

You can drop the parentheses around 4 - 5y. (4 - 5y) is the same as 4 - 5y.

But you must expand (multiply out) -2(3.5y - 8). The result is
-7y + 16 Here we are applying the Distributive Property of Multiplication.

Now combine 4 - 5y and - 7y + 16. Result: -12y + 20 (answer)

If you need clarification here, please ask!

Answer 2

(4 - 5y) - 2(3.5y - 8)

first distribute

(4- 5y) - 7y + 16

Then simplify
-12y + 20

Then simplify

4(-3y + 5)

hope this helps
