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