Solving Ax = b: Row Reduced Form R -- Lecture 8. Learn how to solve equations that look like Ax = b using row reduced echelon form (rref).
• How do you solve Ax = b?
• What is row reduced echelon form?
• What is rref?
• When does Ax = b not have a solution?
This video explains how to find the solution to a matrix equation Ax = b, and to determine when there will not be a solution. The process used in this video is elimination to get to row reduced echelon form.

Very nice video sir. I am really impressed by your lecture. In fact, I didn't get a single word in my mind from the our class teacher. All my concepts are cleared here. Today, I am watching your video and tomorrow is my final exam. But I am 100% sure that I am going to get a good grade in linear algebra.
