Method to Follow

To solve this problem, you need to:

  • Start by simplifying the first equation
  • Find the value of a
  • Use this value in the second equation
  • Isolate b

Step 1: Simplify

a² + a² + a² = 27
3a² = 27

Step 2: Find a

a² = 9
a = 3 or a = -3

Step 3: Find b

a + b = 18

If a = 3:
b = 18 − 3 = 15

If a = -3:
b = 18 − (−3) = 21

Result

b = 15 or b = 21

Conclusion

This challenge shows that a simple equation can lead to multiple solutions. It highlights the importance of thoroughly solving each step and not forgetting that a squared equation can yield two possible values.
