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):

Additional information on creating matrices, matrix operations, and matrix
applications in linear algebra is presented in Chapters 10 and 11 of the
calculator's User's Guide.
