None of these really do. The associative property is about regrouping things being added, such as
   (3+5)+7 = 3+(5+7)

Someone could I guess argue the “4+2y+7x+8” used it, by dropping the parentheses and thereby changing the grouping to just be the standard left-to-right that the order of operations dictates. But that’s a pretty lame answer if that’s what the person is going for.

Answer:

(3,-4) or x=3 and y= -4

Step-by-step explanation:

I'm going to solve this by substitution

We first need to get a variable by itself in one of the two equations (it doesn't matter which variable and the equation you do the work on doesn't matter either)

I'm going to solve for y in the second equation

-4x-4y=4

add 4y and subtract 4 from both sides to get

-4x-4=4y

Divide by 4 to get

-x-1=y

We can plug this value in for y into the first equation and get

4x+5(-x-1)= -8

Solve for x

4x-5x-5= -8

-x-5= -8

-x= -3

x=3

We can plug this value into one of the first two equations and solve for y

4(3)+5y= -8

12+5y= -8

5y= -20

y= -4

Therefore the solution is (3,-4) or x=3 and y= -4
