Question 921429
arnold is as old as the combined age of his two brothers, bart and charly, but charly is two years older than bart. If arnold is 6 years old, how old is bart now?
---------------
Equations::
a = b + c
c = b+2
a = 6
-----
Substitute:
b+c = 6
b-c = -2
---
Add to solve for "b":
2b = 4
bart = 2 yrs old
