Question

Х : 40 – 54 = 6746; 494 + (54 · 75 - x) : 25 = 569

Answer 1

X : 40 - 54 = 6746
x : 40 = 6746 + 54
x : 40 = 6800
x = 6800 : 40
x = 170
Ответ: 170

494 + (54 · 75 - x) : 25 = 569
494 + (4050 - x) : 25 = 569
(4050 - x) : 25 = 569 - 494
(4050 - x) : 25 = 75
4050 - x = 75 · 25
4050 - x = 1875
-x = 1875 - 4050
-x = -2175
x = 2175
Ответ: 2175
