Solve the following system using augmented matrix methods: -2x+4y= -14 4x - 7y= 25 (a) The initial matrix is: Al (b) First, perform the Row Operation R₁ R₁. The resulting matrix is: (c) Next, perform the operation -4R₁ + R2 → R₂. The resulting matrix is: 9- 94 (d) Finish simplifying the augmented matrix. The reduced matrix is: 9. x = 9- (e) How many solutions does the system have? If infinitely many, enter "Infinity". y = 9- (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 y solutions let y = t and solve for æ in terms of t.
