−6x+2y=−32

4x+3y=−9

1 answer

To solve the system of equations:

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

we can use the substitution or elimination method. Here, I'll use the elimination method.

First, we can simplify Equation 1 by dividing all terms by 2:

\[ -3x + y = -16 \quad \text{(Equation 1 simplified)} \]

Now, we can isolate \(y\) in Equation 1:

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

Next, we'll substitute Equation 3 into Equation 2:

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

Distributing the \(3\):

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

Combine like terms:

\[ 13x - 48 = -9 \]

Now, add \(48\) to both sides:

\[ 13x = 39 \]

Then, divide by \(13\):

\[ x = 3 \]

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

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

Thus, the solution to the system of equations is:

\[ x = 3, \quad y = -7 \]

In ordered pair form, the solution is \((3, -7)\).
