Age Word Problem
Age word problems are problems involving ages of one person or two or more persons. Problems deal with the ages of people currently, in the past or in the future.
Let us analyze the given problem.
What is asked?
The age of Maria.
What are the given?
John's Age - 6 years old
Maria's Age - two more than twice the age of her brother John
What is the equation?
To find the age of Maria, we need to translate the given word expression of her age to an equation.
"two more than twice the age of her brother John"
2 + 2(6) = N
We need to use addition because of the phrase "more than". Then, we have "2(6)" since we need to get the twice of John's age.
What is the solution?
2 + 2(6)
= 2 + 12
= 14
What is the final answer?
Maria is 14 years old.

Translating Words to Equations
Here are some examples of translating words to equations.
- the sum of 8 and 10 = 8 + 10
The word "sum" tells us that we need to add the two quantities.
The word "less than" tells us that we need to subtract and we need to write them backwards.
- 3 more than thrice of 5 = 3 + 3(5)
Addition for the phrase "more than" then we need to multiply 5 by 3 because of the word "thrice".
