Решите плес (6.227-3 х) : 0.08+16.4=90

(6,227-3 х) + 0,8+16,4=90

(6227/1000 - 3 х) : 2/25 + 82/5 = 90

(6227/1000-3 х) * 25/2 + 82/5 = 90

6227/80 - 75/2 х + 82/5 = 90

7539/80 - 75/2 х = 90

7539 - 3000 х = 7200

-3000 х - 7200 - 7539

-3000 х = - 339

х = - 3000: (-339)

х = 113/1000

x = 0,113

(6,227-3 х) : 0,08+16,4=90

(6,227-3 х) : 0,08=90-16,4
