my brother is 13 years older than me
If your brother is 13 years older than you, it means there is a 13-year age gap between the two of you.
If your brother is 13 years older than you, the first step is to determine your age. To do this, subtract 13 from your brother's age. Let's assume your brother is 30 years old. In this case, you would subtract 13 from 30.
30 - 13 = 17
So, your age would be 17 if your brother is 13 years older than you.
To determine your brother's age, we need to add your age to the age difference between you and him.
Let's assume your age is represented by X. Since your brother is 13 years older than you, his age can be represented as X + 13.
Therefore, your brother's age is X + 13.
