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

### Instruction:
Cassidy collects movie posters from newly released sci-fi movies. After this summer, she will have six more posters in her collection, making it double the size it was two years ago when she had 14 posters. How many posters does she have now?

### Response:
 Acha x iwe idadi ya picha ambazo Cassidy anazo sasa.
Baada ya msimu huu wa kiangazi, atakuwa na picha mara mbili ya ile aliyokuwa nayo miaka miwili iliyopita, hivyo atakuwa na x + 6 = 2 * 14 = 28 picha.
Hivyo, Cassidy anayo picha x = 28 - 6 = 22 sasa.
