Помагите решить уравнения​

Могу только одно извини времени нет, 64-x=91:7

64-x=13

X=64-13

X=51

64-51=91:7

13=13

1. 64 - x = 13

x = 64 - 13

x = 51

2. 600 - x = 401

x = 600 - 401

x = 199

3. 4980 - x = 2010

x = 4980 - 2010

x = 2970

4. 45 - x = 18

x = 45 - 18

x = 27

5. 600 - x = 9

x = 600 - 9

x = 591

6. 76854 - x = 3000

x = 76854 = 3000

x = 73854

7. 14000 - x = 68 * 9

x = 14000 - 612

x = 13388

8. 604 - x = 210

x = 604 - 210

x = 394

9. 703 - x = 675

x = 703 - 675

x = 28

10. 879 - x = 696

x = 879 - 696

x = 183
