and [MATH]B[/MATH] is a matrix based on any column of [MATH]A[/MATH].
what does this mean?
In all cases?Because B is not included in calculating r (A|B)
I will let you decide. Was there anything special about your A and B or were they just arbitrary matrices?In all cases?

By the way, how do you determine the rank of a matrix? How about the rank of a system of equations?
Thats what I'm trying to know ?How does the matrix B obtained does influence the rank of the matrices?
How do you determine the rank of a matrix? How do you determine the rank of a system of equations? You answered those--thank you.Thats what I'm trying to know ?
There isn't any difference. You just have to put the system of equations as an augmented matrix and find the rank...How do you determine the rank of a matrix? How do you determine the rank of a system of equations? You answered those--thank you.
Now I have a different question. What is the differences, if any between the two methods?
So use that as your justification as why the two ranks are equal?There isn't any difference. You just have to put the system of equations as an augmented matrix and find the rank...
I don't understand that question.So use that as your justification as why the two ranks are equal?
Got it ! Thank youSo use that as your justification as why the two ranks are equal?
