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

### Instruction:
Tracy, Michelle, and Kati take a road trip that is a total of 1000 miles.  Tracy drives 20 miles more than twice Michelle, and Michelle drives 3 times the amount that Katie drives. How many miles does Michelle drive?

### Response:
 เราจะให้ x เป็นจำนวนไมล์ที่เคทีขับ
มิเชล: 3x
เทรซี: 20+2(3x)=20+6x
รวม: x+3x+20+6x=1000
10x+20=1000
10x=980
x=<<98=98>>98 ไมล์
3(98)=<<3*98=294>>294 ไมล์
