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:

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