Question

Х+8=12. а-7=30. 47-b=34

Answer 1

х + 8 = 12

х = 12 - 8

х = 4

а - 7 = 30

а = 30 + 7

а = 37

47 - b = 34

b = 47 - 34

b = 13

Answer 2

Х= 12-8

Х=4

-------------

4+8=12

12=12

а=30-7

а= 23

-------------

23+7=30

30=30

b=47-34

b=13

--------------

47-13=34

34=34

Answer 3

To solve these equations:

1. Х+8=12 Subtracting 8 from both sides: Х = 4

2. а-7=30 Adding 7 to both sides: а = 37

3. 47-b=34 Subtracting 34 from both sides: 47 - 34 = b b = 13

Therefore, the solutions are: Х = 4, а = 37, b = 13.
