### Solving Systems of Equations Using Matrix Inverses
#### Problem Statement
Use the given inverse of the coefficient matrix to solve the following system:
\[
\begin{aligned}
7x_1 + 2x_2 & = -8 \\
-6x_1 - 2x_2 & = -2
\end{aligned}
\]
Given Matrix Inverse:
\[
A^{-1} = \begin{pmatrix}
1 & 1 \\
-3 & \frac{7}{2}
\end{pmatrix}
\]
#### Choose the Correct Solution
Select the correct choice below and, if necessary, fill in the answer boxes to complete your choice.
- **Option A**: \(x_1 = \) [ ] and \(x_2 = \) [ ] (Simplify your answers.)
OR
- **Option B**: There is no solution.
---
#### Explanation of Diagrams and Graphs:
In this problem, the inverse of the coefficient matrix \(A^{-1}\) is provided, which is used to solve the system of linear equations. The elements within the matrix are displayed in a 2x2 format:
- The first row of the matrix is \((1, 1)\)
- The second row of the matrix is \((-3, \frac{7}{2})\)
Your task involves using this matrix inverse to find values of \(x_1\) and \(x_2\).
