Answer 2

х * 8 = 25 + 15

х * 8 = 40

х = 40 : 8

х = 5

Проверка:

5 * 8 = 40

40 = 40

_______________

(43 - 39) * х = 24

4 * х = 24

х = 24 : 4

х = 6

Проверка:

(43 - 39) * 6 = 24

4 * 6 = 24

24 = 24

________________

12 : х + 10 = 13

12 : х = 13 - 10

12 : х = 3

х = 12 : 3

х = 4

Проверка:

12 : 4 + 10 = 13

3 + 10 = 13

13 = 13
