The solution to the system of equations is x = -3 and y = 0.

The given system of equations is:

Equation 1: y = -3x - 9

Equation 2: 3x + 4y = -9

To find the solution to this system, we need to find the values of x and y that satisfy both equations simultaneously.

We can start by substituting Equation 1 into Equation 2:

3x + 4(-3x - 9) = -9

Simplifying the equation:

3x - 12x - 36 = -9

Combine like terms:

-9x - 36 = -9

Now, let's isolate the variable x:

-9x = -9 + 36

-9x = 27

Divide both sides of the equation by -9 to solve for x:

x = 27 / -9

x = -3

Now that we have the value of x, we can substitute it back into Equation 1 to find the value of y:

y = -3(-3) - 9

y = 9 - 9

y = 0

Therefore, the solution to the system of equations is x = -3 and y = 0.
