Answer 1

Составим уравнение
Х + 4х = 20
5х = 20
Х = 20 ÷ 5
Х = 4 (л) - осталось в канистре


Или
Одну часть оставили, а забрали 4 таких частей. Следовательно всего 5 равных частей.
20 ÷ 5 = 4 (л) -

Answer 2

Problem Analysis

We are given that there were 20 liters of gasoline in a canister. After pouring out several liters, the amount of gasoline remaining in the canister is four times greater than the amount poured out. We need to determine how many liters of gasoline are left in the canister.

Solution

Let's assume that x liters of gasoline were poured out of the canister. According to the given information, the amount of gasoline remaining in the canister is four times greater than the amount poured out. Therefore, the amount remaining is 4x liters.

We can set up the following equation to represent the given information:

20 - x = 4x

To solve for x, we can simplify the equation:

20 = 5x

Dividing both sides of the equation by 5, we get:

x = 4

Therefore, 4 liters of gasoline were poured out of the canister. To find the amount of gasoline remaining, we substitute this value back into the equation:

20 - 4 = 16

There are 16 liters of gasoline remaining in the canister.

Answer

There are 16 liters of gasoline remaining in the canister.
