Use Gauss - Jordan Elimination to solve the following system of equations: 4x - 2y + z = -5 5x + y + 3z = 6 -2x + 3y + 2z = -4 Answer: Gauss-Jordan Elimination is only good for square matrices, i.e. same number of equations as variables. Select one: O True O False Given the following 3x3 system of equations, write the augmented matrix. System x - 4y + 3z = 5 -x + 3y - z=-3 2x - 42 = 6 Select one: O a. 1 3 -1 2 0 O b. 1 -4 3 -1 3 -1 -3 N 0 -4 6 O C. 3 -1 3 -1 0 -4 O d
