Question 793956
George is 2 years older than Sam and Sam is 3 years older than Alex. 
The total of their ages is 35. 
Write and solve the equation to find the ages of George, Sam, and Alex.
-------
Equations:
g = s + 2
g = a + 3
g + s + a = 35
------
Substitute for s and for a, ad solve for "g"::
g + g-2 + g-3 = 35
3g - 5 = 35
3g = 40
================
g = 40/3 = 13 1/3 yrs (George's age)
-----
s = 13 1/3 -2 = 11 1/3 yrs (Sam's age)
------
a = 13 1/3 - 3 = 10 1/3 yrs (Alex's age)
