Linux Is 4 Years Older Than Jocelyn And Erin Is Twice As Old As Linux. The Sum Of Their Ages Is 48. How Old Is Linux?
In this article, we will delve into a mathematical puzzle that involves three characters: Linux, Jocelyn, and Erin. The problem states that Linux is 4 years older than Jocelyn and Erin is twice as old as Linux. Additionally, the sum of their ages is 48. Our goal is to determine the age of Linux.
Understanding the Problem
Let's break down the information provided in the problem:
- Linux is 4 years older than Jocelyn.
- Erin is twice as old as Linux.
- The sum of their ages is 48.
We can represent the ages of Linux, Jocelyn, and Erin using variables. Let's use L to represent Linux's age, J to represent Jocelyn's age, and E to represent Erin's age.
Setting Up the Equations
Based on the information provided, we can set up the following equations:
- L = J + 4 (Linux is 4 years older than Jocelyn)
- E = 2L (Erin is twice as old as Linux)
- L + J + E = 48 (The sum of their ages is 48)
Solving the Equations
We can start by substituting the expression for E into the third equation:
L + J + 2L = 48
Combine like terms:
3L + J = 48
Now, we can substitute the expression for L into this equation:
3(J + 4) + J = 48
Expand the equation:
3J + 12 + J = 48
Combine like terms:
4J + 12 = 48
Subtract 12 from both sides:
4J = 36
Divide both sides by 4:
J = 9
Now that we have found Jocelyn's age, we can find Linux's age by substituting J into the first equation:
L = J + 4 L = 9 + 4 L = 13
Conclusion
In this article, we have solved a mathematical puzzle involving three characters: Linux, Jocelyn, and Erin. By setting up equations based on the information provided, we were able to determine Linux's age. The final answer is that Linux is 13 years old.
Additional Insights
This problem can be solved using algebraic methods, but it can also be approached using logical reasoning. For example, we can start by finding the age of Erin, which is twice as old as Linux. Since Linux is 4 years older than Jocelyn, we can find Jocelyn's age by subtracting 4 from Linux's age. Once we have Jocelyn's age, we can find Linux's age by adding 4 to Jocelyn's age.
Real-World Applications
This type of problem can be applied to real-world scenarios, such as:
- Determining the age of a person based on their relationship to another person.
- Calculating the total cost of a project based on the cost of individual components.
- Finding the value of a variable in a mathematical equation.
Final Thoughts
In conclusion, this article has demonstrated how to solve a mathematical puzzle involving three characters: Linux, Jocelyn, and Erin. By setting up equations and using algebraic methods, we were able to determine Linux's age. This type of problem can be applied to real-world scenarios and can help develop problem-solving skills.
