Choose the statement(s) that correctly describe the system. X - 2y - Z 0 -7x + y Z = 3 -15x + 4y Z = 11 Select all that apply. The system is inconsistent. The system has a unique solution. The system is dependent. 0 (13' -130) O The system has no solution. O (-78-39a, -39 - a, a) The system's complete solution can be written as 6+3a _3+8a 13 13 , a ), where a is any real number. The system has infinitely many solutions
