Answer:

x=-3 and y=-3

Step-by-step explanation:

Given the following simultaneous equations:

6x-6y=0\\3x+y=-12\\

We take the first equation and rearrange it:

6x-6y=0\\6x-6y+6y=0+6y\\6x=6y\\x=y

We can substitute in the second equation to find the value of x:

3x+x=-12\\4x=-12\\x=-3

Since x=y therefore y=-3.
