1. In some cases, a matrix may be row reduced to more than one matrix in reduced row echelon form, using different sequences of row operations


2. The row echelon form of a matrix is unique


3. The positions of the leading 1's in the row echelon form of the matrix depend on whether row interchanges are used during Gausian elimination


4. Whenever a system has free variables , the solution set contains many solutionsIndicate whether each statement is true or false justify by giving a logical argument or counterexample......?
