Use Gauss-Jordan elimination to solve the linear system and determine whether the system has a unique solution, no solution, or infinitely many solutions. If the system has infinitely many solutions, describe the solution as an ordered triple involving variable z.4x - y + 3z=12x + 4y + 6z=-325x + 3y + 9z=20
