A Correct answer
Explanation

Let Alvira's age be x. 45 = 2x + 15. 30 = 2x, so x = 15.

AI explanation

Let Alvira's age be A. The father's age is 15 years older than twice Alvira's age, giving the equation 2A + 15 = 45. Subtracting 15 from both sides yields 2A = 30. Dividing by 2 gives Alvira's age as 15 years.
