3. [-/1 Points] DETAILS LARLINALG8 1.1.065. 0/5 Submissions Used MY NOTES ASK YOUR TEACHER State why the system of equations must have at least one solution. (Select all that apply.) 7x + 7y Z = 0 14x + 7y + 42 = 0 7x + 21y - 132 = 0 During the elimination process, we obtain a false statement. The system contains three equations and three variables. The point (x, y, z) = (0, 0, 0) solves the system. During the elimination process, we obtain the equation 0 = 0. The point (x, y, z) = (1, 1, 1) solves the system. Solve the system and determine whether it has exactly one solution or Infinitely many solutions. (If the system has an infinite number of solutions, express x, y, and z in terms of the parameter t.)
