Below is an instruction that describes a task. Write a response that appropriately completes the request in French. Please answer in French.

### Instruction:
 Kaylin is five years younger than Sarah, who is twice as old as Eli, who is nine years older than Freyja. If Freyja is ten years old, how old is Kaylin?


### Response:
 Puisque Freyja a dix ans, Eli a 10+9 = <<10+9=19>>19 ans.
L'âge de Sarah est le double de celui d'Eli, donc Sarah a 2*19= 38 ans.
Kaylin est cinq ans plus jeune que Sarah, donc elle a 38-5 = <<33=33>>33 ans.
