Question

Решите задачу составив уравнение.В двух бидонах находится керосин.В первом было 8л керосина.когда из него перелили 3,4л керосина во второй бидон то во втором бидоне стало на 2,3л керосина больше чем в первом. сколько литров керосина было во втором бидоне первоночально?

Answer 1

(х+3,4)-(8-3,4)=2,3

х-8+6,8=2,3

х=8-6,8+2,3

х=3,5

проверка:

(3,5+3,4)-(8-3,4)=2,3

6,9-4,6=2,3

2,3=2,3

 

Answer 2

(х+3.4)-(8-3.4)=2.3

х-8+2(3.4)=2.3

 х-8+6.8=2.3

х=2.3+8-6.8

х=10.3-6.8

х=3.5(л) 

Answer 3

Problem Analysis

We are given two containers with kerosene. Initially, the first container has 8 liters of kerosene. When 3.4 liters of kerosene are poured from the first container into the second container, the second container ends up with 2.3 liters more kerosene than the first container. We need to find out how many liters of kerosene were initially in the second container.

Solution

Let's assume that the initial amount of kerosene in the second container is x liters.

According to the problem, when 3.4 liters of kerosene are poured from the first container into the second container, the second container ends up with 2.3 liters more kerosene than the first container.

So, the amount of kerosene in the second container after pouring is (8 - 3.4) liters, which is equal to (x + 2.3) liters.

We can write this as an equation:

(8 - 3.4) = (x + 2.3)

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

Solving the Equation

To solve the equation, we can simplify both sides:

(8 - 3.4) = (x + 2.3)

Simplifying the left side:

4.6 = (x + 2.3)

Next, let's isolate x by subtracting 2.3 from both sides:

4.6 - 2.3 = x

Simplifying further:

2.3 = x

Therefore, the initial amount of kerosene in the second container was 2.3 liters.

Answer

The initial amount of kerosene in the second container was 2.3 liters.
