![### Solving a System of Equations Using Gauss-Jordan Elimination
Given the system of linear equations:
\[
\begin{align*}
3x_1 + 3x_2 - 7x_3 &= -13 \\
4x_1 + 18x_2 - 43x_3 &= -9 \\
x_1 + 3x_2 - 7x_3 &= -3
\end{align*}
\]
### Determine the Correct Solution
Select the correct choice below and fill in the answer box(es) within your choice.
#### A. The unique solution is \( x_1 = \) [Box] \( x_2 = \) [Box] and \( x_3 = \) [Box].
#### B. The system has infinitely many solutions. The solution is \( x_1 = \) [Box] \( x_2 = \) [Box] and \( x_3 = t \).
(Simplify your answers. Type expressions using \( t \) as the variable.)
#### C. The system has infinitely many solutions. The solution is \( x_1 = \) [Box] \( x_2 = s \) and \( x_3 = t \).
(Simplify your answer. Type an expression using \( s \) and \( t \) as the variables.)
#### D. There is no solution.
To solve the system, you would use the Gauss-Jordan elimination method to transform the system into row echelon form or reduced row echelon form. Once in one of these forms, you'll be able to see the solutions or determine if there are none.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fcc2e02f5-ed43-48ba-8577-f130ad68cab1%2F3d972960-cb16-4d07-a55c-badb64cc76b1%2Fzdqii7d_processed.jpeg&w=3840&q=75)
