Hello all, I'm really sorry that this may come across as a ridiculously simple question, but I'm taking a linear algebra class online with a teacher who is no help at all. I was hoping somebody could guide me through the process to solve this problem. Please be as thorough as possible for me. Thank you in Advance. Let A = matrix whose columns are u; v: 2 -4 A = 3 2 4 1 Solve the equation Ax = b: (and I think it's giving me the answer here, but I'm not sure cause I can't even begin to solve the problem) [ -4 8 ] Please help if you can. Thank you.
