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. x + y + z = 7 x - y + 2z = 7

A. (8, -3, 2)
B.
C. (-3z + 14, 2z - 7, z)
D. (4, 1, 2)
