Math Problem Statement
Sam is twenty-six years older than Brian. Eight years from now, Sam will be three times as old as Brian. Find their present age
Solution
Let's solve this problem step-by-step by defining variables and setting up equations based on the information given.
Step 1: Define Variables
- Let represent Sam's current age.
- Let represent Brian's current age.
Step 2: Translate the Problem into Equations
-
Sam is twenty-six years older than Brian:
-
Eight years from now, Sam will be three times as old as Brian:
- Eight years from now, Sam's age will be .
- Eight years from now, Brian's age will be .
- The equation based on the second condition is:
Step 3: Solve the Equations
First, substitute the expression for from the first equation into the second equation:
Simplify the equation:
Rearrange the equation to group the terms on one side:
Divide by 2 to find :
Now, find using the first equation:
Step 4: Conclusion
- Brian's current age: years
- Sam's current age: years
So, Brian is 5 years old and Sam is 31 years old.
