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 given 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

From the problem statement, 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)

We can substitute the expression for E from the second equation into the third equation:

L + J + 2L = 48

Combine like terms:

3L + J = 48

Now we have two equations and two variables:

L = J + 4 3L + J = 48

Solving the System of Equations

We can solve this system of equations using substitution or elimination. Let's use substitution.

Rearrange the first equation to isolate J:

J = L - 4

Substitute this expression for J into the second equation:

3L + (L - 4) = 48

Expand and simplify:

4L - 4 = 48

Add 4 to both sides:

4L = 52

Divide both sides by 4:

L = 13

Conclusion

We have solved the system of equations and found that Linux is 13 years old.

Checking Our Answer

Let's check our answer by plugging L = 13 into the original equations:

  • L = J + 4 => 13 = J + 4 => J = 9
  • E = 2L => E = 2(13) => E = 26
  • L + J + E = 48 => 13 + 9 + 26 = 48 (True!)

Our answer checks out!
