To analyze the system of inequalities \( x < -2 \) and \( x \geq 3 \):
- The inequality \( x < -2 \) includes all values to the left of -2 on the number line.
- The inequality \( x \geq 3 \) includes all values starting from 3 and moving to the right on the number line.
Since there is no overlap between the two inequalities (one is to the left of -2, and the other is to the right of 3), there are no values of \( x \) that satisfy both inequalities simultaneously.
Therefore, the correct description is:
The system has no solutions.
