5. Solve (for x) the following systems of equations. Note that some of the systems may not have a unique solution: if so, you should state that (with evidence). In all cases, in addition to giving the solution, give the determinant of the coefficient matrix; that is, give det(A), where A is the matrix in the equation Ax = b.
