Question

Напишите пожалуйста решение подробное<br />Один вложил 7 мл, Второй вложил 8мл. Общая прибыль 6 мл. Какая прибыль у первого и какая у второго?

Answer 1

7+8=15 млн общая вложенная сумма
7/15 из неё вложил первый и 8/15- второй.
тогда найдём 7/15 от прибыли и отдадим её первому, а 8\15- второму
7/15*6=2 4/5=2,8 млн первому
8/15*6=3 1/5=3,2 млн второму
ты про это

Answer 2

Solution:

To solve this problem, we can use a system of equations to represent the given information and then solve for the individual profits.

Let's assume: - The profit of the first person is represented by x. - The profit of the second person is represented by y.

Given: - The first person invested 7 million. - The second person invested 8 million. - The total profit is 6 million.

We can set up the following system of equations: 1. x + y = 6 (total profit is 6 million) 2. 7x + 8y = 6 (individual profits based on the investments)

Now, let's solve the system of equations to find the individual profits.

Solving the System of Equations:

We can use the substitution method to solve the system of equations.

From equation 1, we can express x in terms of y: x = 6 - y

Substitute the value of x in equation 2: 7(6 - y) + 8y = 6

Simplify the equation: 42 - 7y + 8y = 6 42 + y = 6 y = 6 - 42 y = -36

Now that we have the value of y, we can find the value of x: x = 6 - (-36) x = 6 + 36 x = 42

Answer:

- The profit of the first person is 42 million. - The profit of the second person is -36 million.

It's important to note that the negative value for the second person's profit may indicate a loss rather than a profit, which should be considered in the context of the problem.
