Question

На двух машинах был 2400 кг картофеля.После того как с первой машины продали 600 кг,а со второй-400 кг , на обеих машинах картофеля стало поровну. Сколько кг картофеля стало на каждой машине?

Answer 1

Решение:
2400 - (600 + 400) = 1400 (кг) в обоих машинах
1400 : 2 = 700 (кг) в каждой машине

Ответ: в каждой машине осталось по 700 кг картофеля.

Answer 2

Х-кг. в каждой машине
(Х-600)+(Х-400)=2400
2Х-1000=2400
2Х=2400-1000=1400
Х=1400:2
Х=700 кг
700+600=1300 кг. в 1-й машине
700+400=1100 кг.-во 2-й машине

Answer 3

Calculating the Distribution of Potatoes on Two Cars

To solve this problem, we can use a system of linear equations. Let's denote the amount of potatoes on the first car as x and the amount on the second car as y. We are given the following information: 1. The total amount of potatoes on both cars is 2400 kg: x + y = 2400. 2. After selling 600 kg from the first car and 400 kg from the second car, the remaining amounts are equal: (x - 600) = (y - 400).

Solving the System of Equations

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

First, let's express y in terms of x using the first equation: y = 2400 - x

Substitute this expression for y into the second equation: (x - 600) = ((2400 - x) - 400)

Now, solve for x: x - 600 = 2400 - x - 400 2x = 3000 x = 1500

Substitute the value of x back into the expression for y: y = 2400 - 1500 y = 900

Conclusion

So, after solving the system of equations, we find that there were 1500 kg of potatoes on the first car and 900 kg of potatoes on the second car.

Therefore, there were 1500 kg of potatoes on the first car and 900 kg of potatoes on the second car.
