Question: Find the augmented matrix [A|b] when Ti = 30, T2 = 09, T3 = 20 and T4 = 10. Use MATLAB to find the reduced

Find the augmented matrix [A|b] when Ti = 30, T2 = 09, T3 = 20 and T4 = 10. Use MATLAB to find the reduced row echelon form of the augmented matrix from question 1. Using your solution from question 2, find the value of x. Use MATLAB to find A-1. Use MATLAB to find x using the equation x = A b. Note that this answer should be the same as the answer you obtained in question 3. Which method did you find easier to use when solving for x? Using the reduced row echelon form to find x or using A- to find x
