Suggest one further small extension or improvement of your own to the modified flashcard program. Outline what the extension does and briefly say what additional sub-problem(s) would need to be added to the initial decomposition. Note that you are only required to describe your further extension and do not need to implement it in code. The maximum word count is 150 words, including the added sub-problem(s).

Task 9   You are asked by your line manager to implement a computer code for solving the following system of linear equations using MATLAB. You need to upload your code as to be assessed as a part of this assignment. 4x1 + 1x2 + 2x3 − 3x4 + 5x5 = −16 −3x1 + 3x2 − 1x3 + 4x4 − 2x5 =   20 −1x1 + 2x2 + 5x3 + 1x4 + 3x5 =   −4   5x1 + 4x2 + 3x3 − 1x4 + 2x5 = −10   1x1 − 2x2 + 3x3 − 4x4 + 5x5 =     3 then prove it

using python language Create a tuple called triple of size 3 containing the numbers 1,2,3 Create three separate variables x, y, z and use the tuple triple to initialize the values Create a separate tuple called quad of size 4 (with numbers 1,2,3,4) and try to initialize the values, what happens? Tuples support slicing, make some modifications if possible using slicing to fix this problem.
