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

### Instruction:
Ali, Peter, and Joey were fishing. The fish Ali caught weighed, in sum, twice as much as the fish that Peter caught. Joey caught 1 kg more fish than Peter. Together the three of them caught 25 kg of fish. How many kilograms did Ali catch?

### Response:
 กำหนดให้ x = น้ำหนักของปลาที่พีเตอร์ตก
อาลี = 2*x
โจอี้ = x + 1
x + 2*x + x + 1 = 25
4*x + 1 = 25
4*x = 24
x = <<6=6>>6
อาลี = 2*x = 2*6 = 12
อาลีตกปลาได้ 12 กิโลกรัม.
