Question: point) Consider the following two systems. -4x+ y = -3 -3x - 9y = 3 -4x+ y = -2 -3x - 9y = - 2

point) Consider the following two systems. -4x+ y = -3 -3x - 9y = 3 -4x+ y = -2 -3x - 9y = - 2 Find the inverse of the (common) coefficient matrix of the two systems. A-1 = i) Find the solutions to the two systems by using the inverse, i.e. by evaluating A-1B where B represents the right hand side (i.e. 3 -2 for system (a) and B = for system (b)). 3 -2 olution to system (a): x = y= olution to system (b): = = U =
