Directions of Vectors and Substitution and Elimination Methods for Solving Linear Systems of Equations
1. Explain why vectors QR and RQ are not equivalent.
2. Explain when the elimination method for solving a system of equations is preferable to the substitution method.
It is extremely important for you to show your work. This helps me immensely, as I am much better working backwards when it comes to math problems and solutions.
