14. (6 points) There are two barrels of wine, A and B. If 8 kilograms of wine are added to barrel A, the two barrels will weigh the same. If 3 kilograms of wine are transferred from barrel A to barrel B, the wine in barrel B will be 3 times that in barrel A. Barrel A originally had $\qquad$ kilograms of wine, and barrel B had $\qquad$ kilograms.
【Solution】Solution: According to the problem, we have:
If 3 kilograms of wine are taken from bucket A and poured into bucket B, the difference between the two buckets is: $8+3+3=14$ (kilograms);
At this point, bucket A has: $14 \div(3-1)=7$ (kilograms);
Bucket B has: $7 \times 3=21$ (kilograms);
Bucket B originally had: $21-3=18$ (kilograms);
Bucket A originally had: $18-8=10$ (kilograms).
Answer: Bucket A originally had 10 kilograms of wine, and bucket B had 18 kilograms.
Therefore, the answers are: 10, 18.
