Реши уравнение (223440-130*x) : 35=6020 (31*550-x) * 120=10200

1) (223440 - 130 * х) : 35 = 6 020

223440 - 130 * х = 6020 * 35

223440 - 130 * х = 210700

130 * х = 223440 - 210700

130 * х = 12740

х = 12740 : 130

х = 98

Проверяем:

(223440 - 130 * 98) : 35 = 6020

(223440 - 12740) : 35 = 6020

210700 : 35 = 6020

6020 = 6020

2) (31 * 550 - x) * 120 = 10200

31 * 550 - x = 10200 : 120

31 * 550 - x = 85

17050 - х = 85

х = 17050 - 85

х = 16965

Проверяем:

(31 * 550 - 16965) * 120 = 10200

(17050 - 16965) * 120 = 10200

85 * 120 = 10200

10200 = 10200
