Помогите решить уравнения.

x / (100.000 - 99.955) = 16.560 / 45

8.704 + x = 89 * (57.269 - 49.993)

x * (375 + 25) / 5 = 1.586 + 30.414

X: (100.000-99.955) = 16560:45

x:45=16560:45

x:45=368

x=368*45

x=16560

16560: (100.000-99.955) = 16560:45

8704+x=89 * (57.269-49.993)

8704+x=89*7276

8704+x=647.564

x=647.564-8704

x=638.860

8704+638.860=89 * (57.269-49.993)

x * (375+25) : 5=1586+30.414

x*400:5=1586+30.414

x*80=32.000

x=32.000:80

x=400

400 * (375+25) : 5=1586+30.414
