Answer

The sum of Willie's age and his father's age is $3y-2$ years.

Work Step by Step

Willie is $y$ years old. In order to find his father's age, which is twice his age minus $2$, we must multiply his age by $2$, and then subtract $2$. When we multiply $y$ by $2$, we get $2y$. When we subtract $2$ from $2y$, we get $2y-2$. To find the sum of their ages, we must add their ages: $y+(2y-2)=y+2y-2=3y-2$
