Question 6(a)(5 marks) Use determinants (i.e. Cramer's Rule) to solve the system of equations below. Note that if you use a different method then you will get zero marks for this question, even if you get the correct solution. 4.2 + 5y = 5 3x + 4y= 9 Question 6(b) (3 marks) 3 3 Suppose you are given matrices A = and B If possible, evaluate BT - 3A. 2 2 Question 6(c) (4 marks) if possible, evaluate AB for the matrices A and B in Question 6(b).
