1. (a) Use Gauss Elimination to determine the solution of the following system of equa- tions: -12 213 = 3 +13 =0 -212 = 3 0 (b) Use Gauss-Jordan elimination to find A- where A = ON (c) Use part (b) to re-solve Ar = b. (d) Determine whether the following vectors are linearly independent. Justify your answer. (e) For what values of a does the following system of equations have no solutions. -12 -213 3 +13 = 3
