Welcome to the PF. Please tell us more about your question, and what you have learned so far about systems of equations and how the determinant is used in the solution. What can you say about the system of equations if the determinant is zero?

In general, if Ax= y and the determinant of A is 0, there is not a single solution. There may be NO solution of an infinite number of solutions, depending upon both A and y.
