1.8*(0.3x+11.6)=34.542 решите уравнение 10

1.8(0.3х + 11.6) = 34.542

0.54х + 20.88 = 34.542

0.54х = 34.542 - 20.88

0.54х = 13.662

х = 25.3

1,8 х ( 0,3Х + 11,6) = 3, 542
0,54Х + 20, 88 = 34,542
0,54Х =34,542 - 20, 88
0,54Х =13, 662
Х =13, 662 : 0, 54
Х =25, 3
 проверка: 
1,8 х ( 0,3 х 25,3 + 11,6) =34, 542
                           34, 542 = 34, 542
