I am a TikZ newbie and am struggling to create a plot showing three planes and their point of intersection for the following system of linear equations:
I would like to have something similar (or better!) than this plot that I have generated using GeoGebra:
During my search process, I came across this solution, which when expanded will give me what I want, but I am unsure on what to change in the code to create the planes based on the equations. Thanks for help in advance!
