Ok, here is one of the questions I have. I have several but I will just do one at a time. Please reply if you can help me with steps or answer or anything. Like I said, I am new at this but I thought it might be helpful. Thanks in advance for the help.
Use Elementary row operations to write the matrix in echelon form:
[2 4 2 6]
[-2 1 3 4]
[3 2 1 5]
If you know that answer, that is great, I am just really stumped on this weeks work.
