Hi Li,

Sorry, I assumed that these vectors were in two dimensions. So my suggestions about parallel lines won't work :-(

However, it still seems that the solution can be simplified like so. Determining if any point in in both lines is equivalent to finding solutions the the following system of linear equations

This is obtained from

I think the current solution is okay. But as you suggested, we can add another way to prove there's no solution to

using the matrix you mentioned above.
