Solve the following system of equations two ways: • First solve using elementary row operations (you may use back-substitution if you like). Make sure you annotate your work clearly. • Second solve by expressing the system as a matrix equation of the form Ax = b (make sure you provide some explanation of where this matrix comes from.), find A-¹, and then multiply both sides of the equation with A-¹. Here is your system of equations: x+y=z= 4 2xy + z = 2 -3x + y + 5z = 2 Make sure to submit a clear, complete, and detailed solution. Include all of your steps. No determinants may be used for this problem.
