85x + 74x + 42x + 1474x = 86562
85x + 74x + 42x + 1474x = 86562(85 + 74 + 42 + 1474)x = 86562(1675)x = 86562x = 86562 / 1675x ≈ 51.68
Ответ: x ≈ 51.68
85x + 74x + 42x + 1474x = 86562
85x + 74x + 42x + 1474x = 86562
(85 + 74 + 42 + 1474)x = 86562
(1675)x = 86562
x = 86562 / 1675
x ≈ 51.68
Ответ: x ≈ 51.68
