August undefined, 2024

WebThis method gives us a way to solve any matrix equation of the form 𝐴 𝑋 = 𝐵 if matrix 𝐴 is invertible. However, this method cannot be used when 𝐴 is not invertible. This could happen if 𝐴 is not a square matrix or if 𝐴 is square and d e t 𝐴 = 0. In such cases, the matrix equation has either an infinite number of solutions or no solution.
