Question

Не понимаю уравнение 410 860+m*20=489 000

Answer 1

410860 + m × 20 = 489000
m × 20 = 489000 - 410860
m × 20 = 78140
m = 78140 ÷ 20
m = 3907.
Ответ : m = 3907.

Answer 2

$410860 + m \times 20 = 489000 \\ m \times 20 = 489000 - 410860 \\ m \times 20 = 78140 \\ m = 78140 \div 20 \\ m = 3907$
