Answer:
- Cristiano gave 13 apples to his brother.
Explanation:
We know that:
- Cristiano = 42 apples
- Cristiano's brother = 16 apples
Since Cristiano has more apples than his brother, Cristiano must give his apples to his brother. Let's name Cristiano as C and his brother as B.
- => C - x = B + x
- => 42 - x = 16 + x
- => 42 + 16 = x + x
- => 58 = 2x
- => x = 29
This means that when Cristiano has equal apples to his brother, they will have 29 apples.
- => 42 - 29 = Apples given by Cristiano.
- => 13 = Apples given by Cristiano
Hence, Cristiano gave 13 apples to his brother.
