solve the system of equations.

Question

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

Answer 1

To solve this system of equations, we can start by subtracting the second equation from the first equation:

6x - 3y - (9x - 3y) = -6 - (-18)
6x - 3y - 9x + 3y = -6 + 18
-3x = 12
x = -4

Now we can substitute the value of x back into either equation to solve for y. Let's substitute into the first equation:

6(-4) - 3y = -6
-24 - 3y = -6
-3y = 18
y = -6

Therefore, the solution to the system of equations is x = -4, y = -6.
