For this case we have to:

x: Be the variable that represents the age of Catie's brother

y: Be the variable that represents Catie's age

So, we have:

[tex]y = x + 3\\x + y \leq31[/tex]

Substituting the first equation in inequality we have:

[tex]x + (x + 3) \leq31[/tex]

Answer:

[tex]x + (x + 3) \leq31[/tex]
