Solution With The Inverse Matrix; Solution By "Division" Of Matrices - HP 50g User Manual

A solution was found as shown next.

Solution with the inverse matrix

The solution to the system A x = b , where A is a square matrix is
-1
x = A b . For the example used earlier, we can find the solution in the
calculator as follows (First enter matrix A and vector b once more):

Solution by "division" of matrices

While the operation of division is not defined for matrices, we can use the
calculator's / key to "divide" vector b by matrix A to solve for x in the
matrix equation A x = b . The procedure for the case of "dividing" b by A
is illustrated below for the example above.
The procedure is shown in the following screen shots (type in matrices A
and vector b once more):
