As I was experimenting on my Ti-Nspire, I found a cool nsolve() trick
using x and y on the regular Ti-Nspire..
Example - guessing the perimeter of a 2000 feet in a square area:
nsolve(x*2+y*2=2000,x)|y=200.
I use the at sign and chosen a number for y.
nsolve(x*2+y*2=2000)|y=200. x=800.
2000 feet is 200+200+800+800. 2000 foot perimeter.
