Answer:

10 years old

Step-by-step explanation:

Let's put own the data given to us.

Alyssa (a) = 2b

Brittany (b)

Jazmyn (j) = a + 15 = 2b + 15 = 35

Let us solve the equation.

2b + 15 = 35

      2b = 35 - 15

      2b = 20

         b = 20 / 2

         b = 10

Therefore, Brittany is 10 years old.
