Answer:
   The system will be found to be inconsistent or dependent.
Step-by-step explanation:
The matrix A will have no inverse for two different reasons:
- The system is inconsistent
- The system is dependent
In the latter case, the Gauss-Jordan method will find a set of parametric equations for a solution. In the former case, there is no solution.
The outcome will depend on the reason why there is no inverse.
