Question

32,4 : (7, 06х-101,2)*1,8=1,458

Answer 1

32,4:(7,06х-101,2)*1,8 = 1,458

32,4:(7,06х-101,2) = 1,458:1,8

7,06х-101,2 = 32,4:0,81

7,06х - 101,2 = 40

7,06х = 40+101,2

7,06х = 141,2

х = 141,2:7,06

х = 20

Проверяем:

32,4:(7,06*20-101,2)*1,8 = 32,4:40*1,8 = 0,81*1,8 = 1,458

Ответ: 20.
