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

### Instruction:
 杰森厌倦了附近的动物搜刮他的垃圾。他用胡椒喷雾喷了一些浣熊和6倍于浣熊数量的松鼠。如果他总共喷了84只动物，他喷了多少只浣熊？


### Response:
 设喷了浣熊的数量为r，喷了松鼠的数量为s。我们知道r + s = 84，且s = 6r。
将第二个方程代入第一个方程，得到r + 6r = 84
合并同类项，得到7r = 84
两边同时除以7，得到r = 12
