Answer:
Maria is 9 years old
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
