19. A student started solving a system using Gaussian Elimination and didn’t finish. Use Gaussian Elimination to finish solving the system. (Use elementary row operations to write the matrix in row-echelon form.) You must clearly state what elementary row operation you use for each step. (e.g., 8R, + R, → R, , R, → R,) State the solution as an ordered triple. 1 -1 2 2 0 -3 11|-5 2 -1 1 9.
