"WebOne equation defines a plane. Two equations define two planes: and in geometry, two planes intersect in a line. Thus these two equations define a line, and you know this just because there are two of them. A third equation would define another plane, and the intersection of that plane and the line you have already got would give you a point. " - How do i know if an equation has one solution
