Solved: Use the method of Gauss-Jordan elimination
Chapter 3, Problem 22P(choose chapter or problem)
Use the method of Gauss-Jordan elimination (trails–forming (lie augmented matrix into reduced echelon form) to solve Section 3.2.In Problems, use elementary row operations to transform each augmented coefficient matrix to echelon form. Then solve the system by back substitution.3x1 + x2 ? 3x3 = 62x1 + 7x2 + x3 = ?92x1 + 5x2 = ?5
