Вопрос:
Решите уравнение.
1) (14+x) - 35 = 41;
2) (x - 43) + 64 = 70;
3) (95-x) - 13 = 55;
4) 875-(x-761) = 328;
5) 703 - (652 - x) = 566;
6) 888 - (x + 364) = 419.
Ответ:
- (14 + x) - 35 = 41
14 + x = 41 + 35
14 + x = 76
x = 76 - 14
x = 62
- (x - 43) + 64 = 70
x - 43 = 70 - 64
x - 43 = 6
x = 6 + 43
x = 49
- (95 - x) - 13 = 55
95 - x = 55 + 13
95 - x = 68
x = 95 - 68
x = 27
- 875 - (x - 761) = 328
875 - x + 761 = 328
1636 - x = 328
-x = 328 - 1636
-x = -1308
x = 1308
- 703 - (652 - x) = 566
703 - 652 + x = 566
51 + x = 566
x = 566 - 51
x = 515
- 888 - (x + 364) = 419
888 - x - 364 = 419
524 - x = 419
-x = 419 - 524
-x = -105
x = 105
