with a 2x2 matrix Consider the following system of linear equations. 5x-20y=-40 -9x+40y=80 Solve the system by completing the steps below to produce a reduced row-echelon form. R, and R, denote the first and second rows, respectively. The arrow notation (- means the expression/matrix on the left becomes the expression/matrix on the right once the row operations are performed.
