Let -6-(-2x-y) = 0

open the bracket
-6+2x+y= 0
Adding 6 on both sides you will get
2x+y = 2

Now put any value of x in order to get the value of y like

Let x = 2 then
2(2)+y=6
4+y = 6
y=6-4
y=2
So if x=2 then y = 2

Let x = 4
2(4)+y=6
8+y=6
y=6-8
y=-2
So if x=4 then y = -2 and so on.

Rule:

(-)(-)=+
(-)(+)=-
(+)(-)=-
(+)(+)=+

Let -6-(-2x-y) = 0
Now solve the brackets first you will get

-6+2x+y = 0
Adding 6 on both sides you will get
-6+2x+y +6 = 0+6

2x+y = 6

The original question gave only an expression, not an equation. Is there some reason you chose to make this expression equal 0, not some other number?
