I'm basing that on just transcribing the text and putting it into google translate with "detect language" turned on. That said I also assumed it'd be a Slavic language too, but I don't think any of them use the ү character that's in the second word on the second line, whereas Mongolian, other Mongolic languages, and Turkic languages often do when written in Cyrillic. The first word is "avtomashin", but Mongolian got that word from Russian

Edit: transcriptions

Автомашин

• тай бүх зургийг сонгоно уу

Roughly Romanised, just using Wiktionary's versions (I do not know how to pronounce any of this myself)

Avtomašína

• Tai büx zurgiig songono uu

Assuming I've got that right, it's quite definitely not Slavic

And then the machine translation from Mongolian
