Problem Analysis

We are given two warehouses, and the amount of firewood in one warehouse is twice the amount in the other warehouse. If we add 80 tons of firewood to the first warehouse and 145 tons to the second warehouse, the amount of firewood in both warehouses will be equal. We need to find the initial amount of firewood in each warehouse.

Solution

Let's assume the initial amount of firewood in the first warehouse is x tons. According to the problem, the amount of firewood in the second warehouse is twice that of the first warehouse, so it will be 2x tons.

After adding 80 tons of firewood to the first warehouse, the total amount of firewood in the first warehouse becomes x + 80 tons. Similarly, after adding 145 tons of firewood to the second warehouse, the total amount of firewood in the second warehouse becomes 2x + 145 tons.

According to the problem, the total amount of firewood in both warehouses is equal. Therefore, we can set up the following equation:

x + 80 = 2x + 145

Now, let's solve this equation to find the value of x.

x + 80 = 2x + 145

Subtract x from both sides:

80 = x + 145

Subtract 145 from both sides:

80 - 145 = x

Simplify:

-65 = x

Therefore, the initial amount of firewood in the first warehouse is -65 tons. However, this is not a valid solution because the amount of firewood cannot be negative. It seems there might be an error in the problem statement or the given information.

Unfortunately, the search results provided by You.com do not provide any relevant information to help us solve this problem. Therefore, we cannot determine the initial amount of firewood in each warehouse based on the given information.
