To solve this system of equations, we can first notice that both equations have -3y terms. We can subtract the first equation from the second equation to eliminate the y terms.
(9x - 3y) - (6x - 3y) = -18 - (-6)
3x = -12
x = -4
Now that we have found the value of x, we can substitute it back into the first equation to solve for y.
6(-4) - 3y = -6
-24 - 3y = -6
-3y = 18
y = -6
Therefore, the solution to the system of equations is x = -4, y = -6.
(9x - 3y) - (6x - 3y) = -18 - (-6)
3x = -12
x = -4
Now that we have found the value of x, we can substitute it back into the first equation to solve for y.
6(-4) - 3y = -6
-24 - 3y = -6
-3y = 18
y = -6
Therefore, the solution to the system of equations is x = -4, y = -6.
