- Hello Mia! I’m trying to find a gift for Camille, a friend of mine that I haven’t seen in a long time. I need to know her age so that I can give her an appropriate present. It is embarrassing to ask her directly, so I resorted to asking her brother, Alexander, instead.
- Hey Aliyah! What are you up to?
- Oh, so that's why I struggled to answer. I slept during class that time and didn’t bother to listen well. When I found out we would be having a test, I did not think much of it. I decided to study only from the book thinking it was all there. The mistake of not listening attentively was made by me. I truly regret my actions.

- Oh hello Aira. Honestly, I found the test really confusing and hard. I think I failed it.
- Oh, maybe I can help. Let’s hear it.
- The problem is... he gave me a math problem instead of simply answering. I don’t know how to solve this, but I need to know Camille’s age.
- Yes! Thank you Mia for your help, now I will be able to find a proper gift. And maybe I just might think of a way to get back at Alexander for complicating things... just kidding!
- That is an age problem my friend! I can surely help you with that.
- 38 - 22 is equal to 16 right? Does that mean Camille is 16 years old now?
- Alexander said that in 5 years, he would be 27 years old. The current sum of ages of Camille and Alexander is 38. Now the question is, “What is Camille’s age right now?”
- The current sum of their ages is 38 right? So if we put what we know into an equation, it will look like: 22 + x = 38
- You mentioned that Alexander is 27 years old in 5 years, so to find out his current age, we just need to subtract 5 from 27. This means that Alexander is 22 years old now.
- .
- Exactly! See, it wasn’t so hard right? Now we know that Camille is 16 years old.
- Since we don’t know Camille’s current age, we can represent it as “x”
- To solve this, we could transpose 22 to the right. It is the rule that we should change the sign of the transposed term. Our current equation will now be: x = 38 - 22
