9y-%28-4y-2x%29
The tricky part here is to recognize the implications of that minus sign in front of the parenthesis. Think of it as a -1 multiplying everything inside the parenthesis, like this:
9y%2B%28-1%29%28-4y-2x%29
Now, when you "remove" the parenthesis, you can see that you are really multiplying through by -1:
9y%2B4y%2B2x
Now, you can combine "like" terms for the final answer:
highlight%2813y%2B2x%29
Good Luck,
