Question: How do I solve a matrices problem in Maple

Enter the matrix

To prevent typing errors you may copy and paste following Maple command for entering A.

A := Matrix([[4, 7, 5, 2, 6, 4, 9, 7, 5, 8, 5], [7, 7, 3, 9, 4, 5, 2, 3, 5, 6, 8], [5, 6, 5, 6, 6, 3, 7, 4, 9, 1, 9], [9, 1, 4, 8, 9, 4, 4, 2, 1, 3, 3], [5, 6, 8, 2, 2, 1, 2, 9, 5, 4, 1], [4, 7, 9, 6, 9, 2, 3, 5, 6, 3, 5], [7, 2, 5, 7, 3, 4, 9, 8, 1, 8, 9], [5, 7, 1, 2, 7, 9, 9, 2, 2, 4, 7], [1, 6, 5, 3, 9, 9, 1, 5, 7, 4, 2], [3, 7, 8, 7, 8, 3, 6, 4, 6, 9, 2]]);

[Note that Maple does not display the full matrix when it has more than 10 rows or 10 columns.  However, you can still work with the matrix using Maple commands.]

Use Maple to create the vector b that is column 6 from A and the matrix C that is made from columns 1 to 5 and 7 to 11 of A (in the same order as the columns of A).

Now solve the matrix equation

C x = b

and enter the 6^th component of the unique vector solution for x in the box below.  (Your answer should be an exact fraction, not a decimal)

The answer is 63695593/46022164

Can someone help me out?

Cheers.
