Theorem 1: If A is a non-singular matrix, then the system of equations given by `AX = B` has the unique solution given by `X = A^-1 B`

If A is a non-singular matrix then |A^(-1)| =

If is a non-singular matrix, then det (A^(1))=

Let AX=B be a system of n-linear equations in n-unknowns ( in the usual notation ) such that A is a non singular matrix , then the system is consistent and has a unique solution given by
