# Vectors and Matrices watch

I'm still really confused, so if then ; would you just say that as the relation?
Yeah a=1 and b=-1 is one answer.

I think the relation is a=3+2b.
(a-1=2+2b add 1 to both sides)

That's giving you all of the values of a and b such that the matrix is consistent and has at least one solution, so I think that is the final answer.

No problem.
I know what you mean. Lecturers that give solutions, or even just numerical answers are my faves.
