Solve the system of equations

6x - 3y = -6
9x - 3y = -18

To solve the system of equations, we will use the method of substitution or elimination.

1. Let's first simplify the equations:
6x - 3y = -6
9x - 3y = -18

2. Since both equations have the variable term -3y, we can set this term equal in both equations:
-3y = -6
-3y = -18

3. Solve for y:
-3y = -6
y = 2

-3y = -18
y = 6

4. Now, substitute the value of y back into one of the equations to solve for x:
6x - 3(2) = -6
6x - 6 = -6
6x = 0
x = 0

So, the solution to the system of equations is x = 0 and y = 2.
