This, I think is pre-algebra, not pre-calculus...

The line V passes through the points (-5,3) and (7,-3) and the line W passes through the points (2,-4) and (4,2). The lines V and W intersect the point A. Work out the coordinates of the point A.

How do I do this? Please do step by step. I have worked out the equation of both lines in the form ax + by + c = 0.

V -> $\displaystyle x + 2y -1 = 0$

W -> $\displaystyle 3x-y-10=0$

EDIT: I've been thinking it through some more. I know that both x and y have to be the same for both lines. Would I be right in thinking of using simultaneous equations to work this out?
