My names is Shaun and I am $13$ years old.
I find this an important question to ask, because we can solve a system of four variables, but we think we cannot graph it. Yes, I agree, as humans who sadly cannot visualize $4D$, we would not be able to answer this question in depth. However, we know it is possible to graph it, as all the lines intersect at a specific point.
And if we can visualize it (as I have researched on many websites, like Wikipedia, Quora, Stack Exchange and so forth), then how can we visualize it? Through lines, or shapes$?$ Colours maybe$?$
When I say we can solve a system of four variables, I mean that we solve equations like this:
$w^2+x^2+y^2+z^2 = 8 $
$x^2w^2 + z^2y^2 = 4 $
Does anyone, who is experienced enough, know how to answer this question$?$
