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.
Directions of Vectors and Substitution and Elimination Methods for Solving Linear Systems of Equations are investigated. The solution is detailed and well presented. The response received a rating of "5/5" from the student who originally posted the question.
