Answer:

$5y+4$

Step-by-step explanation:

What we know:

- 3 × $y$ is equal to Sara's father's age

- $y$ + 4 is equal to Sara's brother's age

- $y$ is equal to Sara's age

Sum of their ages = father's age + Sara's age + brother's age

Sum of their ages = $3y+y+(y+4)$

Sum of their ages = $5y+4$

I hope this helps!
