12a + a = 455
13a = 455
a = 35 adults
c = 12(35) = 420 kids

What
Damon is 18, Damon's brother is 11 years old.
So, the total age of them both is 29. Damon is 7 years older, so we use 29-7=22. Now, 22 is Damon's brother's age times 2, so we use 22/2=11. 11 is Damon's age is 11+7=18, and His brothers age is 11.
Hope it helped!
