Advanced algebra is required to solve this challenge. You should read Perplexing Protons before beginning this challenge.
We left an unsolved equation after solving Perplexing Protons. In this challenge, we will solve it. Good luck!
x=5\,000\,000+E^+\frac{2-e^ {\frac{-1}{N^+}}-e^\frac{-3}{N^+}}{N^+} +E_{t=3.25}-3E^+-1\\[8pt] \frac{E^+-E^+e^\frac{-3}{N^+}} {N^+e^\frac1{N^+}}=1\,000\,000
