What each word does
viagem
trip or journey

viajem

How to choose
- viagem: Choose viagem if the sentence points to the noun naming travel from one place to another.
- viajem: Choose viajem if the sentence points to a present-subjunctive or imperative form of the verb viajar.
Examples
A viagem de trem foi tranquila.

The verb keeps j before e: que eu viaje, que eles viajem. The noun remains viagem.
Practice it in context
Pick one sentence from your real life and write it twice: once with viagem, then once with viajem. If both versions feel possible, name the meaning shift.
