The first container contains 3 liters of water more than the second. If you pour 9 liters of water from the first container into the second, then in the second container there will be 2 times more than will remain in the first. How many liters of water are there in each container?
Let the second container “x” l of water. In the first container there is 3 liters of water more, which means in the first container “x + 3” liters of water. If you pour 9 liters of water from the first container into the second, then in the first container there will be “x + 3-9” liters of water, and in the second there will be “x + 9” liters of water. Knowing that after that, there will be 2 times more water in the second container, we make an equation. 2 * (x + 3 – 9) = x + 9; 2 * (x – 6) = x + 9; 2x – 12 = x + 9; 2x – x = 9 + 12; x = 21 (l) in the second container. 1) x + 3 = 21 + 3 = 24 (l) in the first container.
