urgent, intersection of two planes 1. The problem statement, all variables and given/known data Find the equation of the intersection between 2x + 3y - 4z = 12 and 5x + 2y + 3z = 7. 2. Relevant equations none. I don't know how to use cross products, but is there another way? 3. The attempt at a solution I don't know how to do this and it will be on my final tomorrow... I tried various things but right now the closest I have is, set x to 0 and find for y and z. Please help, I have no idea what else to do. I know it is in this form (or at least, I think it is): [x, y, z] + t(a, b, c) but what are those? t is for time. is the x y z a point on the plane, and how would I find that?
