Answer: Emma is 8, Charlotte is 13, and Sandy is 26. 26 + 13 + 8 = 47

Explanation:

First you need to figure out Emma's age. I did this by writing it out as such:

Emma + (Emma +5) + 2x (Emma +5) = 47

(Emma) (Charlotte) (Sandy)

Then I grouped similar things:

4x (Emma) + 15 = 47

Subtract 15 from both sides:

4x (Emma) = 32

Divide both sides by 4:

Emma = 8

To find Charlotte's age:

8 + 5 = 13

To find Sandy's age:

13 x 2 = 26

Check:

26 + 13 + 8 =47
