Sagot :

Final answer:

Dexter is twice Johnny's age now, and in 10 years, he will be thrice Johnny's age.


Explanation:

Dexter is currently X years old and Johnny is Y years old. We can set up the following equations:

  1. X = 2Y
  2. X + 10 = 3(Y + 10)

Solving these equations simultaneously gives us X = 20 and Y = 10. Therefore, Dexter is 20 years old, and Johnny is 10 years old.
