However, solving equations that involve matrix multiplication is much more involved, since matrix multiplication is complex. So, here’s how we are going to solve equations such as. Step . 1 The symbol x-1 indicates the multiplicative inverse of a number or object. Example: 3-1 = . This means that the multiplicative inverse of 3 is because ...

The back substitution for solving x once the A matrix is reduced to triangular matrix requires O(n2) operations each time the solution is found. If the same matrix A is to be used repetitively to solve for x, it would then make sense to decompose the matrix A such that the repetitive solution would only need to involve triangular matrices.
