None. Parallel lines do not intersect in Euclidean geometry.
Parallel lines don't intersect, no matter how many of them there are.
In space with 3 or more dimensions, there are infinitely many pairs of lines that are not parallel and do not intersect.
It depends on how many lines intersect. An infinite amount.
Since the lines that intersect are the equations, if they intersect once they have one solution.
