To solve the system of equations:

  1. \(-6x + 2y = -32\) (Equation 1)
  2. \(4x + 3y = -9\) (Equation 2)

We will use the method of substitution or elimination. Let's use the elimination method.

First, let's manipulate Equation 1 to make it easier to work with. Divide the entire equation by 2:

\[ -3x + y = -16 \quad \text{(Equation 3)} \]

Now we have the modified system of equations:

  1. \(-3x + y = -16\) (Equation 3)
  2. \(4x + 3y = -9\) (Equation 2)

Next, we can express \(y\) from Equation 3:

\[ y = 3x - 16 \]

Now, we can substitute this expression for \(y\) into Equation 2:

\[ 4x + 3(3x - 16) = -9 \]

Simplifying this:

\[ 4x + 9x - 48 = -9 \]

Combining like terms:

\[ 13x - 48 = -9 \]

Now, add 48 to both sides:

\[ 13x = 39 \]

Dividing by 13:

\[ x = 3 \]

Now that we have \(x\), we can substitute \(x = 3\) back into the expression for \(y\):

\[ y = 3(3) - 16 \] \[ y = 9 - 16 \] \[ y = -7 \]

Thus, the solution to the system of equations is:

\[ \boxed{(3, -7)} \]
