Answer:

  Kevin is 6

Step-by-step explanation:

Let k represent Kevin's age now. Then Brendon's age now is (k-3). Two years ago the relationship of their ages was ...

  k-2 = 4((k-3) -2)

  k -2 = 4k -20 . . . . . eliminate parentheses, collect terms

  3k = 18 . . . . . . . . . . add 20-k

  k = 6 . . . . . . . . . . . . divide by 3

Kevin is 6 now.
