Question 410885
I'm having trouble writing equations that models how old in years each of us will be, when our ages add up to 150 years old. I had to use three people's ages 8,28,30. Explain the reasoning which helped you develop your equation?
----
Those three person's ages do not add up to 150 years old.
---
You might use 40,60, and 50 but not 8,28 and 30.
----
If you use a = 40, b = 60, and c = 50
you would get 3 equations:
---
a + b + c = 150
a = b-20
c = b+10
---------
That's an example.
