I'm having a hard time figuring out this question,

Question

" There is only one positive number that satisfies the equation

(greek letter phe) - 1 = 1 / (greek letter phe)

Based on this definition, find the value of phe."

Thanks for the help I really appreciate it.

Answer 1

see above

Answer 2

That's phi, not phe

Ø-1 = 1/Ø
Ø^2-Ø-1 = 0
Ø = (1±√5)/2

pick the positive value
