![### Solving Systems of Equations using Augmented Matrices
Consider the following system of linear equations:
\[
\begin{cases}
2x_1 + 2x_2 = 10 \\
x_1 - x_2 = -3
\end{cases}
\]
To find the solution using augmented matrices, follow the instructions provided in the given problem.
**Instructions:**
Select the correct choice below and, if necessary, fill in the answer box to complete your choice.
**Options:**
- **A.** The unique solution is \( x_1 = \boxed{} \) and \( x_2 = \boxed{} \).
- **B.** The system has infinitely many solutions. The solution is \( x_1 = \boxed{} \) and \( x_2 = t \).
_(Simplify your answer. Type an expression using \( t \) as the variable.)_
- **C.** There is no solution.
**Explanation of options:**
- **Option A:** This option suggests that there is a unique solution for the system. If this is chosen, you need to provide the specific values of \( x_1 \) and \( x_2 \) that satisfy both equations.
- **Option B:** This option indicates that the system has infinitely many solutions. Here, \( x_2 \) can be expressed in terms of a parameter \( t \), and you need to provide the corresponding expression for \( x_1 \) in terms of \( t \).
- **Option C:** This option is stating that there might be no solution for this system of equations.
**Graph/Diagram Analysis:**
This particular problem does not include any graphs or diagrams but focuses on the algebraic process of solving the system of equations.
To solve the system using an augmented matrix:
1. Write the augmented matrix for the system:
\[
\begin{pmatrix}
2 & 2 & | & 10 \\
1 & -1 & | & -3
\end{pmatrix}
\]
2. Perform row operations to obtain the row-echelon form.
3. Determine the values of \( x_1 \) and \( x_2 \) or identify the nature of the solutions based on the resulting matrix.
Now, proceed to solve the system and select the appropriate option from A, B, or C based on your](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F4a1af21b-af18-455d-9657-67bfb10798dd%2F65f8127d-24a0-4e90-8b5e-71f84fa38117%2Fbvq8mwl_processed.png&w=3840&q=75)
