![### Infinite Solutions in Linear Systems
The following system of linear equations has an infinite number of solutions. Our goal is to form an augmented matrix, reduce the matrix, and then write the solution in terms of \( z \).
\[
\begin{align*}
1x + 1y + 3z &= 3 \\
2x - 2y + 1z &= 4 \\
3x - 1y + 4z &= 7 \\
\end{align*}
\]
#### Step 1: Form the Augmented Matrix
An augmented matrix is formed by appending the columns of the constants from the right-hand side of the system to the coefficient matrix:
\[
\left( \begin{array}{ccc|c}
a_{11} & a_{12} & a_{13} & b_1 \\
a_{21} & a_{22} & a_{23} & b_2 \\
a_{31} & a_{32} & a_{33} & b_3
\end{array} \right)
\]
#### Step 2: Reduced Matrix
We then row-reduce this matrix to its reduced form:
\[
\left( \begin{array}{ccc|c}
1 & 0 & \frac{7}{4} & \frac{5}{2} \\
0 & 1 & \frac{5}{4} & \frac{1}{2} \\
0 & 0 & 0 & 0 \\
\end{array} \right)
\]
where the elements of the reduced matrix are given as:
\[
\begin{align*}
a_{11} &= 1, & a_{12} &= 0, & a_{13} &= \frac{7}{4}, & b_1 &= \frac{5}{2} \\
a_{21} &= 0, & a_{22} &= 1, & a_{23} &= \frac{5}{4}, & b_2 &= \frac{1}{2} \\
a_{31} &= 0, & a_{32} &= 0, & a_{33} &= 0, & b_3 &= 0 \\
\end{align*}
\]
#### Step 3: Solution in Terms of \( z \)
Given the reduced form, the system indicates dependency among the](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F30a42a85-c58f-45ac-a4af-faeed1a599e1%2F8eec3d51-b3d2-4d5a-8184-e46955ab937f%2F0b26yy4_processed.png&w=3840&q=75)
