Final answer:
The sentence “Tú soy vieja” is incorrect. The correct form is “Tú eres viejo/a”.
Step-by-step explanation:
The sentence “Tú soy vieja” is incorrect. The correct way to say “You are old” in Spanish is “Tú eres viejo/a”. The verb “soy” is the first person singular form of the verb “ser”, which means “to be”. However, in this case, we are referring to the second person singular pronoun “tú” as the subject, so the correct form of the verb is “eres”.
