Answer:
Step-by-step explanation:
Let v represent Vickey's age now. Then Krishna's age now is 27-v. In 4 years, the sum of their ages is ...
 (27 -v +4) +2(v +4) = 43
 27 -v +4 +2v +8 = 43 . . . . eliminate parentheses
 v +39 = 43 . . . . . . . . . . . . . collect terms
 v +39 -39 = 43 -39 . . . . . . subtract 39 from both sides
 v = 4 . . . . . . . . . . . . . . . . . simplify; this is Vickey's age
 27 -v = 23 . . . . . Krishna's age
Vickey's age is 4; Krishna's age is 23.
