Question

12- +4=14,11- -5=5,13- +8=18,14- -7=3

Answer 1

Ответ:

Пошаговое объяснение:

12 - 2 + 4 = 14

12 - х + 4 = 14

16 - х = 14

х = 16 - 14

х = 2

11 - 1 - 5 = 5

11 - х - 5 = 5

6 - х = 5

х = 6 - 5

х = 1

13 - 3 + 8 = 18

13 - х + 8 = 18

21 - х = 18

х = 21 - 18

х = 3

14 - 4 - 7 = 3

14 - х - 7 = 3

7 - х = 3

х = 7 - 3

х = 4

Answer 2

It appears there might be some mistakes in the calculations you provided. Let's go through them step by step:

1. 12- + 4 = 14: This is incorrect. The correct answer should be 12 - 4 = 8.

2. 11- - 5 = 5: This is incorrect as well. The correct answer should be 11 - (-5) = 16.

3. 13- + 8 = 18: This is incorrect. The correct answer should be 13 - 8 = 5.

4. 14- - 7 = 3: This is incorrect too. The correct answer should be 14 - (-7) = 21.

So the correct calculations should be:

1. 12 - 4 = 8
2. 11 - (-5) = 16
3. 13 - 8 = 5
4. 14 - (-7) = 21
