The difference between the ages of Abigail and her son is 16 years. If Abigail is 32 years old, what is the age of the son.

Let $A$ be Abigail's age and $S$ be her son's age.

The difference between Abigail's age and her son's age is 16 years. Since a mother is typically older than her son, we can write:

The problem states that Abigail is 32 years old, so $A = 32$.
Substitute this value into the equation:

To find $S$, we can rearrange the equation:

The age of the son is $\text{16 years}$.
