According to Google Translate, your message in English is:

Answer in detail. When a cabbage head weighing 3 kg was added to the bag with cabbage, there were 12 kg of cabbage in the bag. How many kg of cabbage were in the bag before this head was added?

To solve this math problem, you can use the following equation:

x + 3 = 12

where x is the amount of cabbage in the bag before adding the 3 kg head.

To find x, you can subtract 3 from both sides of the equation:

x + 3 - 3 = 12 - 3

x = 9

Therefore, the answer is 9 kg. There were 9 kg of cabbage in the bag before adding the 3 kg head.
