Question

Андрей и Олег ловили рыбу. Андрей наловил на 9 рыбок меньше, чем общее кол-во наловленной рыбы, а Олег наловил на 7 рыбок меньше, чем Андрей. Сколько всего рыбок наловили Андрей и Олег вместе ? Помогите заранее спасибо

Answer 1

Х=общее количество рыбы
х-9=Андрей
(х-9)-7=Олег

(х-9)+((х-9)-7)=х
х=25

Андрей - 25-9=16
Олег - 16-7=9

Answer 2

Calculating the Total Number of Fish Caught by Andrey and Oleg

Andrey caught 9 fish less than the total number of fish caught, and Oleg caught 7 fish less than Andrey. To find the total number of fish caught by Andrey and Oleg together, we can use the following steps:

1. Let's assume the total number of fish caught by Andrey is represented by A. 2. And the total number of fish caught by Oleg is represented by O.

Given that Andrey caught 9 fish less than the total number of fish caught, we can express this as: A = (Total number of fish caught) - 9.

Similarly, Oleg caught 7 fish less than Andrey, which can be expressed as: O = A - 7.

To find the total number of fish caught by Andrey and Oleg together, we can add the number of fish caught by Andrey and Oleg: Total = A + O.

Let's calculate the total number of fish caught by Andrey and Oleg together.

Calculation

1. Andrey caught 9 fish less than the total number of fish caught: A = (Total number of fish caught) - 9. 2. Oleg caught 7 fish less than Andrey: O = A - 7. 3. Total number of fish caught by Andrey and Oleg together: Total = A + O.

Solution

1. Andrey caught 9 fish less than the total number of fish caught: A = (Total number of fish caught) - 9. 2. Oleg caught 7 fish less than Andrey: O = A - 7. 3. Total number of fish caught by Andrey and Oleg together: Total = A + O.

By substituting the value of A from the first equation into the second equation, we get: O = (Total number of fish caught) - 9 - 7.

Simplifying, we get: O = (Total number of fish caught) - 16.

Finally, the total number of fish caught by Andrey and Oleg together is: Total = (Total number of fish caught) + (Total number of fish caught - 16).

This can be further simplified to: Total = 2 * (Total number of fish caught) - 16.

Therefore, the total number of fish caught by Andrey and Oleg together is twice the total number of fish caught minus 16.
