Yes, to me it appears that this is no more than what you've already put down.
Sometimes the problems are intriguingly simple.
Write down the system of equations of when and aij = i + j for , , , , while bj = j = 1, ,
2x1 + 3x2 + 4x3 = 1
3x1 + 4x2 + 5x3 = 2
4x1 + 5x2 + 6x3 = 3
Seems like an easy question but not really sure on what they're asking so any clarification will greatly help. Thanks!
