You can put this solution on YOUR website!
You have 3 variables, x, y & z.
You need 3 equations.
----------------------
Each equation defines a plane in 3-space. 2 equations in 3-space can define the intersection of the 2 planes, which is a line (if the planes are not parallel or coincident). All points on the line satisfy both equations.
