Li Bai has nothing to do. He took a hip flask to buy wine, doubled it when he met a shop, drank a bucket when he met flowers, and drank all the wine in the kettle three times. How much wine is there in the original pot? 7/8 Dou meets three shops and three flowers, so the equation should be: Equation: Suppose: there is X fighting wine in the pot. The wine in the pot is 2x- 1 flower after shopping; After the second visit to the store and the flowers, the pot of wine was 2 (2x-1)-1;

The wine in the pot is 2 [2 (2x-1)-1]-1;

So it is related: 2 [2 (2x-1)-1]-1= 0;

Solution: x = 7/8;
