12X - 1000 = 0

No, that's not the equation for your following example.
You are solving 12 xⁿ – 1000 = 0  where n = 1...12.

1 STO 1 f SOLVE then 0 ----> X=83.3333
2 STO 1 f SOLVE then 0 ----> X=9.1287
3 STO 1 f SOLVE then 0 ----> X=4.3679

Do not forget to provide two guesses for x.

Since x must be > 1 you could try 1 [ENTER] 100  [SOLVE] 0.

If you do not enter anything here the solver starts with the two values that happen to be in X and Y. That's certainly not a good idea!
