Solve the following system using augmented matrix methods: (a) The initial matrix is: -3x+6y=-18 7x - 14y = 44 (8818) (b) First, perform the Row Operation R R. The resulting matrix is: (8818) (c) Next, perform the operation -7R + R R. The resulting matrix is: 188 Remaining time: 04:06:25 2= Score summary for last submit: Prob Status Result 1 2 3 y= 4 5 6 (d) Finish simplifying the augmented matrix to reduced row echelon form. The reduced matrix is: [8818) (e) How many solutions does the system have? If infinitely many, enter "Infinity". 7 8 9 10 11 12 13 78% Incorrect 096 Incorrect (f) What are the solutions to the system? If there are no solutions, write "No Solution" or "None" for each answer. If there are infinitely many solutions let y t and solve for a in terms of t. 100% Correct 100% Correct 86% Incorrect 67% Incorrect 0% Incorrect Incorrect 0% 100% Correct 50% Incorrect 100% Correct 75% Incorrect 100% Correct
