Benjamin is 13 and Kevan is 17.

Of the 3 boys, Benjamin is the youngest.
Let Benjamin's age be #x#

Write an expression for the age of each boy:

Benjamin: #x# years old
Kevan : #x+4# years old

William: #2x-4" "larr# double Benjamin's age, less 4.

William is 22 years old.
#2x -4 = 22#

#2x = 26#

#x = 13#

Benjamin is 13 and Kevan is 17.
