6X+6Y=-2 y=-X?
6X+6(-X)=-2
0=-2
not possible
these 2 lines are parallel and dont meet

x=-2

6x + 6y = -2
6(x + y) = -2
x + y = -1/3
so
y = - x be replace inside the equation
x - x = -1/3
not the solution!
i think you post the wrong question

6x-6y=-2
y=-x
6x-6x=-2
0=-2
undefined because it would be -2/0

There is no solution. Simply because if y= - x , then if you substitute it into the first equation 0= -2 which contradicts the first equation that y is equal to -x. Therefore the answer is that there is no solution, and y is not equal to -x

sub in -x for y and you get
6X+6(-X)=-2
so you get
6X-6X=-2
simplified becomes
0=-2
which is an inequality
hope this helps!

-2y = -x
therefore
x = 2y
done
