Brandon is 15 years old.

Let Ian's age be represented by x.
Brandon's age = x + 3

Ian's age + Brandon's age = 27
x + (x + 3) = 27
2x              = 27 - 3
2x              = 24
2x / 2         = 24 / 2
 x               = 12   * Ian's Age.

Brandon's Age = x + 3 = 12 + 3 = 15.
 
To check:

Ian's age + Brandon's age = 27
12 + 15 = 27
27 = 27 
Billymkhoi
Brandon's age+ Ian's age= 27 (years old)
Brandon's age- Ian's age= 3 (years old)

⇒ Brandon's age= (27+3)/2= 30/2= 15 (years old).

Brandon is 15 years old~
