Simple financial math with one quation, can't solve in mathcad prime 4.0

The simple exation with one variable needs numerical solving( with higher potential values compute time climbes a bit), enabled multithreading - not much of a cpu hog ~ 50%(on an i5 2500) - yet no result in prime 4.0

Punched the same quation into WolframAlpha, got an approximated result - due to limited compute time.

Searched though the help tool of the solve function, tried different parameters, still nothing.

Am I blind or missing something -  please enlighten me.(used the thick equation symbol)
Thank you for wasting time on helping me 😉

Mathcad is a numeric solver.  It's symbolic engine is (and always has been) challenged.  A numeric solve block (took longer to type):simple math.PNG

Thanks for kudos!

But when we have 2 or more roots the Find and the root functions can return different answer (different numeric methods!)

PS root works in the free Prime Express - Find - blocked!
