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