Solve the following system using augmented matrix methods: 2x12x2 - 4x3 = 28 5x1+3x21x3 = 4 10x1+6x22x3 = 6 (a) The initial matrix is: 9. (b) First, perform the Row Operation R₁ → R₁. The resulting matrix is: (c) Next, perform the operations -5R₁ + R₂ R₂ -10R₁+R3 R3. The resulting matrix is: 9. (f) What are the solutions to the system? 9. x1 = 9. 9. 9. (d) Finish simplifying the augmented matrix down to reduced row echelon form. The reduced matrix is: 4 9. Remember: This matrix must be simplified all the way to reduced form. (e) How many solutions does the system have? If infinitely many, enter "Infinity". 9.
