Answer 1

Пусть неизвестное число будет x. Составим и решим уравнение:
18-x+4=14
18-x=14-4
18-x=10
x=18-10
x=8
Ответ: 8.

Answer 2

Решим в виде уравнения:
?=х
18-х+4=14
18-х=14-4
18-х=10
18-10=8
х=8

проверка;18-8+4=14
18-8=10
10+4=14


ответ:8

Answer 3

To find the value of the question mark (?), we need to solve the equation:

18 - ? + 4 = 14

Let's simplify the equation step by step:

1. Combine the numbers on the left side: 18 + 4 - ? = 14

2. Simplify the addition: 22 - ? = 14

3. Now, to find the value of ?, we need to isolate it on one side of the equation. To do that, we can subtract 14 from both sides:

22 - 14 - ? = 14 - 14 8 - ? = 0

4. Finally, subtract 8 from both sides to solve for ?:

• ? = -8

5. To get the value of ?, multiply both sides by -1 to change the sign:

? = 8

So, the value of the question mark (?) should be 8.
