Question

Find the solutions to the two systems by using the inverse, i.e. by evaluating ????−1????A−1B where ????B represents the right hand side (i.e. ????=[−2−2]B=[−2−2] for system (a) and ????=[2−1]B=[2−1] for system (b)).

Answer 1

The main systems of equations is missing, but I was able to add one so you can therefore use the same understanding and steps to approach any systems of linear equation.
