Question: Consider the following two systems. (a) 5r + 3y = -2 -x - 3y = -1 (b) 5x + 3y = 1-x - 3y =

Consider the following two systems. (a) 5r + 3y = -2 -x - 3y = -1 (b) 5x + 3y = 1-x - 3y = -1 (i) Find the inverse of the (common) coefficient matrix of the two systems. 1 4 A-1 = 2 (ii) Find the solutions to the two systems by using the inverse, i.e. by evaluating A B where B represents the right hand side (i.e. B = for system (a) and B = for system (b)). Solution to system (a): I = Solution to system (b): I =
