solve the system of equations.

4x - 8y = -36
-6x + y = 32

1 answer

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'll use the substitution method.

First, let's solve Equation 2 for \(y\):

\[ y = 6x + 32 \]

Now, we can substitute this expression for \(y\) into Equation 1:

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

Distribute \(-8\):

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

Combine like terms:

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

Now, add 256 to both sides:

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

\[ -44x = 220 \]

Divide by \(-44\):

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

Now that we have \(x\), substitute it back into the expression we found for \(y\):

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

\[ y = -30 + 32 \]

\[ y = 2 \]

Thus, the solution to the system of equations is:

\[ \boxed{(-5, 2)} \]
