Question

У двох каністрах 15,4 л | | бензину. У першій|каністрі на 3,4 л менше,ніж у другій. Скількибензину в кожнійканістрі? Помогите пож​

Answer 1

Ответ:

6 л бензина в первой канистре, 9,4 л бензина во второй канистре

Пошаговое объяснение:

Х л бензина  во второй канистре

Х - 3,4 л бензина в первой канистре

Х + Х - 3,4 = 15,4

2Х = 15,4 + 3,4

2Х = 18,8

Х = 18,8 : 2 = 9,4 л бензина во второй канистре

9,4 - 3,4 = 6 л бензина в первой канистре

Проверка:

9,4 + 6 = 15,4  - верно

Answer 2

Solving for the Amount of Gasoline in Each Canister

To solve this problem, we can use a system of equations. Let's denote the amount of gasoline in the first canister as x liters and the amount in the second canister as y liters. We are given that the total amount of gasoline in both canisters is 15.4 liters, and the amount in the first canister is 3.4 liters less than the amount in the second canister.

We can express this information in the following system of equations:

1. x + y = 15.4 (total amount of gasoline in both canisters) 2. x = y - 3.4 (amount in the first canister is 3.4 liters less than the amount in the second canister)

Now, let's solve for x and y using these equations.

Solving the System of Equations

Substitute the value of x from equation 2 into equation 1:

y - 3.4 + y = 15.4

Combine like terms:

2y - 3.4 = 15.4

Add 3.4 to both sides:

2y = 18.8

Divide by 2:

y = 9.4

Now that we have the value of y, we can find the value of x using equation 2:

x = 9.4 - 3.4 x = 6

Conclusion

So, the amount of gasoline in each canister is: - 6 liters in the first canister - 9.4 liters in the second canister
