Use the Gauss-Jordan method to solve the system of equations. If the system has infinitely many solutions, give the solution with z arbitrary. 2x - y + 5z = - 10 x+ 2y - 5z = 20 10y + 4z = 32 Select the correct choice below and fill in any answer boxes within your choice. O A. There is one solution. The solution set is {CID) (Simplify your answers.) O B. There are infinitely many solutions. The solution set is {( , z)}, where z is any real number. (Simplify your your answers. Type expressions using z as the variable.) O C. The system is inconsistent. The solution set is Ø.
