I'm confused about whether or not I'm thinking about this correctly:
If I'm given an equation eg. 3x^2-2xy=3z+1 (just a random eg.)
Is it a correct assumption to think of the x,y and z in the equation as corresponding
to x,y and z as I'd think of them on the cartesian plane...They're not just dummy variables
but in this case actually represent something ...like they arent going to switch them around
on me and use y in place of z and x in place of y...
because x=sqrt(y) (right side of parabola) isn't the same as y=sqrt(x) ...so is this
assumption that x and y and z are used on purpose --and arent just 'dummy variables'
