comment What are the implications of $\vec{AB} = \vec{CD}$?
@GrahamKemp: Curious: are $\vec{AB} = \vec{BA}$ considered equal? Or they aren't because the direction is different?

@Rahul: So $1 = 1$?

comment What's wrong with this linear program formulation?
I have added the variables and progressed on the problem. Now I have to solve an expanded program, but I can't find the pivot because $a$ is on the righthand side and I don't know the value of $a$. Does that mean I should have moved $a$ to the lefthand from the beginning?

Oooh, I see - so I need to add two artificial variables, since I already have other two, right?
