Pick a technique that we have learned to solve the following two sets of linear equations: xi +3x2 x3-4 2x2x2+X31 2x 3x2 x3 3 and 4X1 + X2 + X3 + X4=6 3x7x2-X3 X4 1 7x1 3x2-5x38x4-3 xi +X2X32x43 If you know a programming language, 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. If you do not know a programming language, then type the steps of an algorithm that you would systematically follow to apply the technique and solve each set of systems of linear equations above For example, you may select the technique of finding the inverse of the coefficient matrix A, and then applying Theorem 1.6.2:x ATb. There are several ways that we have learned to find A1. Pick one of those ways to code or write as an algorithm. Or another example, you may select Cramer's rule. Within Cramer's rule, there are several techniques that we learned to find the determinant of a matrix. Pick one of those ways to code or write as an algorithm. What to submit: For those who choose to code, submit to me a PDF of the computer code, and a PD 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
