Calculate and state the minimum time for completion

(40%) Based on Gaussian Elimination procedure, write a computer program for solving the system of limear equa- tions with unique solution. Select five systems by yourself and try to solve five systems with your program. It is required that the first is a 1x 1 system (20%), the second is a 2 2 system (20%), the third is a 3 3 systern (20%), the fourth is a 4 4 systern (20%), the fifth is a 5 5 system (20%) List the systems in augmented matrix form and give the solutions from your program
