To solve the problem where \( A = \begin{pmatrix} 1 & 2 \\ 3 & 4 \end{pmatrix} \) and we need to find the matrix \( X \) such that \( AX = I \) (where \( I \) is the identity matrix), we will follow these steps: ### Step 1: Understand the equation We start with the equation: \[ AX = I \] This implies that \( X \) is the inverse of matrix \( A \), denoted as \( A^{-1} \). ...
