1) x + 2,56 = 4
Ответ: x = 1,44
2) 19,7 - x = 6,232
- x = 19,7 - 6,232
- x = 13,468
Ответ: x = 13,468
3) x : 14,158 = 9,842
- x = 9,842 \(\times\) 14,158
- x \(\approx\) 139,285
Ответ: x \(\approx\) 139,285
4) (58 - x) : 41,3 = 6,287
- 58 - x = 6,287 \(\times\) 41,3
- 58 - x \(\approx\) 259,6531
- x = 58 - 259,6531
- x \(\approx\) -201,6531
Ответ: x \(\approx\) -201,6531
