Solve the system of equations. 4x−8y=−36 4 𝑥 − 8 𝑦 = − 36 −6x+y=32 − 6 𝑥 + 𝑦 = 32 (1 point) (, )

1 answer

To solve the system of equations given by:

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

we can first simplify and rewrite these equations.

Starting with the first equation:

Equation 1:

\[ 4x - 8y = -36 \]

We can simplify it by dividing the entire equation by 4:

\[ x - 2y = -9 \]

Now we have:

\[ x = 2y - 9 \] (Equation 3)

Now for the second equation:

Equation 2:

\[ -6x + y = 32 \]

We can express \( y \) in terms of \( x \):

\[ y = 6x + 32 \] (Equation 4)

Now we can substitute Equation 3 into Equation 4 for \( x \):

Substituting \( x \) from Equation 3 into Equation 4:

\[ y = 6(2y - 9) + 32 \]

Now, distribute the 6:

\[ y = 12y - 54 + 32 \]

Combining like terms gives:

\[ y = 12y - 22 \]

Now, isolate \( y \):

\[ -11y = -22 \]

Dividing both sides by \(-11\):

\[ y = 2 \]

Now that we have \( y \), substitute \( y = 2 \) back into Equation 3 to find \( x \):

\[ x = 2(2) - 9 \]

\[ x = 4 - 9 \]

\[ x = -5 \]

So the solution to the system of equations is:

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

Thus, the final answer is:

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