ответ:

1) 1729 - x = 97

- x = 97 -1729

- x = 1632

x = 1632

2) 4300 + x = 7985

x = 7985 - 4300

x = 3685

3) 8408 - x = 4805

- x = 4805 - 8408

- x = -3603

x = 3603

4) 7307 - x = 2739

- x = 2739 - 7307

- x = - 4658

x = 4658

5) x - 583 = 1301

x = 1301 + 583

x = 1884

6) 7158 - x = 4807

- x = 4807 - 7158

- x = - 2351

x = 2351

7) 1 - x = 197

- x = 197 - 1000

- x = - 803

x = 803

8) 5111 - x = 426

- x = 426 - 5111

- x = - 4685

x = 4685

9) x - 1482 = 6508

x = 6508 - 1482

x = 7990

10) x - 6671 = 1925

x = 1925 + 6671

x = 8596

11) x - 1205 = 5078

x = 5078 - 1205

x = 6283

12) 1000 - x = 273

- x = 273 - 1000

- x = - 727

x = 727

13) x - 496 = 308

x = 308 + 496

x = 804

14) 384 + x = 578

x = 578 + 384

x = 194
