To solve the system of equations:

  1. \( 4x - 8y = -36 \) (Equation 1)
  2. \( -6x + y = 32 \) (Equation 2)

We can use the substitution or elimination method. Here, we will use the elimination method.

First, let's rearrange Equation 2 to express \(y\) in terms of \(x\):

\[ y = 6x + 32 \] (Equation 3)

Now, we can substitute Equation 3 into Equation 1:

\[ 4x - 8(6x + 32) = -36 \]

Expanding that gives:

\[ 4x - 48x - 256 = -36 \]

Combining the \(x\) terms:

\[ -44x - 256 = -36 \]

Next, we will add 256 to both sides:

\[ -44x = 220 \]

Now, divide by -44:

\[ x = \frac{220}{-44} = -5 \]

Now that we have \(x\), we can substitute it back into Equation 3 to find \(y\):

\[ y = 6(-5) + 32 \] \[ y = -30 + 32 \] \[ y = 2 \]

Thus, the solution to the system of equations is:

\((x, y) = (-5, 2)\)

So, the answer is: \[ (-5, 2) \]
