Choose the statement(s) that correctly describe the system. X - 2y - Z = 0 -7x + y - Z 5 -15x + 4y - Z = 14 Select all that apply. O The system has a unique solution. The system is dependent. The system has no solution. The system has infinitely many solutions. The system's complete solution can be written as (10+3a _5+8a 13 13 a ), where a is any real number. 0 10 (13' -13 0) The system is inconsistent. D (-130-39a, -65 - a, a)
