Is the word soluções the same in Brazilian and European Portuguese?

Yes

The word "soluções" is identical in spelling, meaning, and grammatical function in both Brazilian and European Portuguese. The only differences are phonetic:

• Vowel Quality: In Brazilian Portuguese, vowels tend to be more "open" and clearly articulated. In European Portuguese, unstressed vowels are often "closed" or even reduced/devoiced, making the word sound more clipped.
• Rhythm: Brazilian Portuguese follows a more syllable-timed rhythm (more musical), whereas European Portuguese is more stress-timed, which can lead to a "swallowing" of certain sounds in the word.
