「 : / (2) Let A- be an arbitrary 2 x 2 matrix. (a) If A is invertible, perform row operations to determine a row echelon form of A. (Hint: You may need to consider different cases, e.g., when a-0 and when a f 0.) (b) Under certain conditions, we can row reduce [A | 2 to [| B] where d -b ad- be-a Use the row echelon form of A from part (a) to find conditions under which the...
1. A Western student paid someone $250 to find elementary row operations transforming the augmented matrix (A|b) to the matrix (1 6 0 -3 010) 0 0 1 4 0 7 (RS) = 0 0 0 0 15 10 0 0 0 0 0 The Western student has no idea what this means, but you do. Assuming the field is R, describe the solution set to the system of linear equations (A[6] (equivalently, the matrix equation AX = b). Your...
