Answer in detail. In the first box there are 27 kg of nails and the same number of nails in the second box. In the third box there are 12 kg of nails less than in the first one. How many kilograms of nails are there in three boxes?

This is a math problem that can be solved by adding and subtracting the weights of the nails in each box. Here is one possible solution:

Let x be the weight of the nails in the first box, y be the weight of the nails in the second box, and z be the weight of the nails in the third box. Then we have:

x = 27 kg y = x z = x - 12 kg

To find the total weight of the nails in three boxes, we need to add x, y, and z. So we have:

x + y + z = 27 kg + 27 kg + (27 kg - 12 kg) = 69 kg

Therefore, there are 69 kg of nails in three boxes.
