How can i do this in Pov?

A)  x=2*y + 1
B) y= x-1

...substitute y's values
x=(2*(x-1))+1
x=(2*x) - 2 + 1
x=(2*x) -1
x-(2*x)=-1
-x=-1
x=1

.. and vice-versa
y=(2*y)+1-1
y=(2*y)
y-(2*y)=0
-y=0
y=0

Is this possible with Pov?

Can it be taken further to stuff like

y=(x*x*x) - (z*z) + 3

... etc


It could be very usefull for checking intersection of objects imo
