Question

Jamie is x years old. His friend Ana is the same age.

Enter an expression in the box to represent the sum of Jamie's and Ana's ages.

Answer 1

Answer: 2x

Step-by-step explanation:

Each person is x years old. Adding those unknown ages gets us x+x = 2x

We can think of it like x being one box, so x+x represents having two boxes which shortens to 2x.
