Question

Составить и решить систему На одном складе угля в 2 раза больше, чем на другом. Если на первый склад привезти ещё 80 тонн, а на другой — 145 тонн, то на обоих складах угля будет поровну. Сколько тонн угля на каждом складе?

Answer 1

Х-2 склад было,стало х+145
2х-1 склад было,стало 2х+80
2х+80=х+145
2х-х=145-80
х=65т было на 2
65*2=130т было на 1

Answer 2

Problem Analysis

We are given two warehouses with different amounts of coal. If we bring an additional 80 tons of coal to the first warehouse and 145 tons to the second warehouse, the total amount of coal in both warehouses will be equal. We need to determine how much coal is in each warehouse.

Solution

Let's assume the amount of coal in the first warehouse is x tons. Since the amount of coal in the second warehouse is twice the amount in the first warehouse, the amount of coal in the second warehouse is 2x tons.

If we bring an additional 80 tons of coal to the first warehouse, the total amount of coal in the first warehouse will be x + 80 tons. Similarly, if we bring an additional 145 tons of coal to the second warehouse, the total amount of coal in the second warehouse will be 2x + 145 tons.

According to the problem statement, the total amount of coal in both warehouses will be equal. Therefore, we can set up the following equation:

x + 80 = 2x + 145

To solve this equation, we can subtract x from both sides:

80 = x + 145

Next, we can subtract 145 from both sides:

80 - 145 = x

Simplifying further:

-65 = x

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

Without additional information or clarification, it is not possible to determine the exact amount of coal in each warehouse.
