![**Problem Statement**:
\( T \) is a linear transformation from \( \mathbb{R}^2 \) into \( \mathbb{R}^2 \). Show that \( T \) is invertible and find a formula for \( T^{-1} \).
\[
T \left( \begin{bmatrix} x_1 \\ x_2 \end{bmatrix} \right) = \begin{bmatrix} 6x_1 - 8x_2 \\ -5x_1 + 7x_2 \end{bmatrix}
\]
**Explanation**:
The problem involves a linear transformation defined by a specific matrix operation. The task is to determine whether the linear transformation \( T \) is invertible and, if so, to find the inverse formula \( T^{-1} \). This process typically involves checking the determinant of the transformation matrix and calculating the inverse matrix if the determinant is nonzero.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F47172a01-dc9c-43a5-97e6-7fd3dbf42a8c%2F2eac55cb-3b15-49b9-ac2f-78f59a10fac7%2Faau1jy_processed.png&w=3840&q=75)
