The total of three sisters' age is 39. Dina is half as old as Michelle and 3 years younger than Juliette. How old are the sisters? Show your work step by step.

Step-by-step explanation:

Let Dina's age = 1/2 x

Let Michel's age = x

Let Juliette's age = 1/2 x + 3

1/2 + x + 1/2x + 3 = 39

2x + 3 = 39

2x = 39 - 3

2x = 36

x = 18

Dina's age = 1/2 18 = 9

Michelle =                18

Juliet = 1/2 18 + 3  = 12

Total                        39
