(1 point) Consider the following two systems. (a) (b) (2x + y = 2 \-x+y = 3 2x+y = -1 -x+y = (i) Find the inverse of the (common) coefficient matrix of the two systems. A-1= -2 [88] (ii) 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. B= system (a) and B: = for system (b)). Solution to system (a): x= Solution to system (b): x= Y y= 23
