И что вас смущает? Знак вопроса?

Хорошо. Заменим его на х. Получим уравнение:

5×5-х×2=11

Решаем)

25 - 2х = 11

-2х = 11-25

- 2х = -14

2х = 14

х = 7

На месте "?" должно быть число 7.

Answer 3

To solve the equation 5x5-?*2=11, we need to find the value of the missing number (?). Let's proceed step by step:

Step 1: Simplify the equation. 5x5 means 5 multiplied by 5, so 5x5 = 25.

Step 2: Rewrite the equation after Step 1. The equation becomes: 25 - ?*2 = 11.

Step 3: Move the constant term (11) to the other side of the equation to isolate the unknown (?). Subtract 11 from both sides: 25 - 11 = ?*2.

Step 4: Calculate the result of the subtraction. 25 - 11 = 14.

Step 5: Rewrite the equation after Step 4. The equation becomes: 14 = ?*2.

Step 6: Solve for ? by dividing both sides of the equation by 2. ? = 14 / 2.

Step 7: Calculate the result. ? = 7.

So, the missing number in the equation is 7.
