Carlos is 5 times less than Sofia's age carlos is 40 years old. How old is Sofia? 1) What does the variable represent in this situation?
2) What operation does less than mean? Times?
3)What expression represents carlos's age?
4) What equation represents this situation?
5) How old is Sofia?

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
