Jamie is x years old. His friend Ana is the same age. Enter and expression in the box to represent the sum of Jamie and Ana ages.

Respuesta :

If Jamie's age is represented as x and given that Ana is the same age as Jamie then, Ana's age can also be represented by x. The sum of their ages is equal to,

          Sum of their ages = x + x

Simplifying,
  
          Sum of their ages = 2x

I took this quiz and the answer is 2x
