What does your textbook say about 1.4.3 (i) Matrix Inversion Method?
This method can be applied only when the coefficient matrix is a square matrix and non-singular. Consider the matrix equation AX = B , … ( ) where A is a square matrix and non-singular. Since A is non-singular, A − exists and A A AA I Pre-multiplying both sides of ( ) by A − , we get A
