I am reading "Linear Algebra" by Strang. In the first lesson, he talks about how to solve equations with 2 unknowns and he shows 2 approaches i,e row approach and column approach. I understand the row approach because it makes sense. I understand the column approach too, but I don't understand how the "column" represents a vector?(adsbygoogle = window.adsbygoogle || []).push({});

BTW I do understand what a vector is and how the vector arithmetic works, but I some how cannot abstract the "column" into vector, in my mind. Can somebody please explain me?

example :

2x - y = 1

x + y = 5
