A plane in three dimensional space can be written as ax + by + cz = d. We can find the possible intersections of planes in this form by writing them as systems of linear equations and using reduction to solve them. If d = 0 in each equation, then we have a homogeneous system with either a unique solution or infinitely many solutions.Determine whether the intersection of the planes:  has a unique solution or infinitely many solutions; then solve the system.

What will be an ideal response?


a unique solution; x = 0, y = 0, z = 0
