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

### Instruction:
Toby has 63 photos on his camera roll. He deletes seven bad shots, takes fifteen pictures of his cat, and then does a photo shoot with his friends. After editing the photos with his friends, he decides to delete three of them. His camera roll has 84 photos in the end. How many photos did Toby take in the photo shoot?

### Response:
 Hebu P iwe idadi ya picha katika picha na marafiki zake.
Baada ya Toby kufuta picha saba, alikuwa na picha 63 - 7 = <<63-7=56>>56.
Baada ya kuchukua picha 15 za paka, alikuwa na picha 56 + 15 = <<56+15=71>>71.
Kisha katika picha na marafiki zake, alipiga P picha.
Baada ya picha na marafiki zake, kamera yake ilikuwa na picha 71 + P.
Baada ya kufuta picha tatu, alikuwa na picha 71 + P - 3 = <<71+-3=68>>68 + P.
Alikuwa na picha 68 + P = 84 mwishoni.
Hivyo, Toby alipiga picha P = 84 - 68 = <<84-68=16>>16 katika picha na marafiki zake.
