![### Matrix Equations and Parameterized Solutions
Here, we will examine two Reduced Row Echelon Form (RREF) matrix equations and convert them into their parameterized solution forms. This is a common exercise in linear algebra to find the set of solutions to a system of linear equations represented in matrix form.
#### Problem Statement
**Convert the following rref matrix equations to parameterized solution form:**
#### Matrix Equation (a)
\[
\begin{pmatrix}
0 & 0 & 1 & 0 & 0 & 0 & 2 \\
0 & 1 & 2 & -1 & 3 \\
0 & 0 & 0 & 1 & 1 \\
0 & 0 & 0 & 0 & 0 \\
0 & 0 & 0 & 0 & 0 \\
0 & 0 & 0 & 0 & 0 \\
\end{pmatrix}
\begin{pmatrix}
x_1 \\
x_2 \\
x_3 \\
x_4 \\
x_5 \\
x_6 \\
x_7 \\
\end{pmatrix}
=
\begin{pmatrix}
1 \\
2 \\
3 \\
0 \\
0 \\
0 \\
\end{pmatrix}
\]
#### Matrix Equation (b)
\[
\begin{pmatrix}
0 & 0 & 1 & 1 & 0 & 0 & 2 \\
0 & 1 & 0 & 1 & -1 & 3 \\
0 & 0 & 0 & 1 & 1 \\
0 \\
0 \\
0 \\
0
\end{pmatrix}
\begin{pmatrix}
x_1 \\
x_2 \\
x_3 \\
x_4 \\
x_5 \\
x_6 \\
x_7 \\
\end{pmatrix}
=
\begin{pmatrix}
1 \\
2 \\
3 \\
0 \\
0 \\
0 \\
\end{pmatrix}
\]
### Explanation
#### Part (a):
1. Identify the pivot positions in the matrix.
2. Express variables corresponding to pivot columns in terms of the free variables.
#### Part (b):
1. Similar to part (a), identify the pivot positions.
2. Express the dependent variables in](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F0d2fdd51-a813-4b36-89e9-f9581acfc2ee%2F453d71d6-2442-405a-a085-ee2205416b35%2Fhguwunp_processed.png&w=3840&q=75)
