The task involves finding the inverse of matrices using two methods:

1. OBE (Operasi Baris Elementer): This method uses row operations to transform the matrix into the identity matrix.
2. Adjoint Method: This method calculates the inverse using the formula: $A^{-1} = \frac{1}{\text{det}(A)} \cdot \text{adj}(A)$ where $\text{det}(A)$ is the determinant of the matrix $A$, and $\text{adj}(A)$ is its adjugate.

Let me know which specific matrix you'd like to start with (as there seem to be multiple matrices in the image), or I can help solve for all the matrices step-by-step.

Would you like a step-by-step guide for one or all matrices?
