Answer 2

Answer:

21

Step-by-step explanation:

Given: Three years ago, Joy was twice as old as Joe

X-3 = 2(x-3) = 2x - 6 ---------------(i)

Joe's age = x ------------------------(ii)

=> 2x - 6 + x = 51

=> 3x - 6 = 51

=> 3x = 57

=> x = 19

Since Joe's age was 19 and it was given that Joy was twice

19 + 2 = 21

Therefore, Joy's age is 21
