You have to subtract 5 from 13
13-5=8 then divide 8 by 2 and get 4
13-5=8 / 2 = 4 
so his sister is 4 years old..

I hope this helps

Answer with Step-by-step explanation:

Let Carlos sister's age be y.

Carlos is 13.

Carlos is five years older than twice his sister's age.

⇒ 13=2y+5

or 2y+5=13

Equation which  correctly identifies his sister's age is:

2y+5=13

⇒ 2y=13-5

⇒ 2y=8

Dividing both sides by 2 gives

y=4

Hence, Carlos sister's age is:

4
