I'm having trouble with these questions:
If given a linear system:
For which values of m and k (unique values or certain sets of values) are the following true:
1: The system has unique solutions
2: The system has no unique solutions
3: There are infinitely many solutions
Or, consider the system of three equations:
For what values of a are the same three conditions above satisfied?
Also, what techniques are used to do these questions in general?
Thanks for all the help in advance
