x1 + 3×2 + x3 = 4
2×1 + 2×2 + x3 = –1
2×1 + 3×2 + x3 = 3
4×1 + x2 + x3 + x4 = 6
3×1 + 7×2 – x3 + x4 = 1
7×1 + 3×2 – 5×3 + 8×4 = –3
x1 + x2 + x3 + 2×4 = 3
Develop a code to read in the input, systematically perform the chosen technique, and then print the output, i.e., the solution to the x-vector for each system.
What to submit:
submit to me a PDF of the computer code, and a PDF
of the screenshots of the input and the output for each set of systems of linear
equations above. Make sure to use comments throughout the code so that I can
understand what each step of the code is performing.
