Question

Нужно решение задачи а не просто ответ.Всего с трех полей собрали 24000 кг картошки.С первого и второго поля собрали 16000 кг , со второго и третьего поля собрали 17000 кг. Сколько собрали с каждого поля?

Answer 1

1) 24000-16000=8 000 (кг) собрали с теретьего поля

2) 24000-17000=7 000(кг) собрали с первого поля

3) 24000-8000-7000=9000(кг) собрали со второго поля

Answer 2

Solution to the Problem

To solve this problem, we can use a system of linear equations. Let's denote the amount of potatoes harvested from the first, second, and third fields as x, y, and z respectively. We are given the following information:

1. The total amount of potatoes harvested from the first and second fields is 16000 kg. 2. The total amount of potatoes harvested from the second and third fields is 17000 kg. 3. The total amount of potatoes harvested from all three fields is 24000 kg.

We can express this information as a system of linear equations:

1. x + y = 16000 (Equation 1) 2. y + z = 17000 (Equation 2) 3. x + y + z = 24000 (Equation 3)

We can solve this system of equations to find the values of x, y, and z.

Solving the System of Equations

Subtracting Equation 2 from Equation 3, we get: x + z = 7000 (Equation 4)

Adding Equation 1 and Equation 2, we get: 2y = 33000 - (x + z) (Equation 5)

Substituting the value of (x + z) from Equation 4 into Equation 5, we get: 2y = 33000 - 7000 2y = 26000 y = 13000 (Equation 6)

Substituting the value of y from Equation 6 into Equation 1, we get: x = 16000 - y x = 16000 - 13000 x = 3000 (Equation 7)

Substituting the value of y from Equation 6 into Equation 2, we get: z = 17000 - y z = 17000 - 13000 z = 4000 (Equation 8)

Conclusion

Therefore, the amount of potatoes harvested from each field is: - 3000 kg from the first field - 13000 kg from the second field - 4000 kg from the third field
