josé's age is 2 more than 3 times maria's age . The sum of their ages is 38 . How old is Maria ?

Sagot :

Answer:

Maria is 9 years old

Step-by-step explanation:

This question can be solved using a system of equations. I am going to say that:

Jose's age is x

Maria's age is y

José's age is 2 more than 3 times maria's age

This means that:

x = 3y + 2

The sum of their ages is 38.

This means that:

x + y = 38

3y + 2 + y = 38

4y + 2 = 38

4y = 38 - 2

4y = 36

y = 36/4

y = 9

Maria is 9 years old
