Ответ:

[tex]7,43b > 7,43c\\b-7,42 > c-7,43\\b+7,42 > c+7,43\\-7,43b < -7,43c[/tex]

Объяснение:

[tex]b > c\ \ \ \ |\cdot 7,43\\\\7,43b > 7,43c[/tex]

[tex]b > c\ \ \ \ |-7,43\\\\b-7,42 > c-7,43[/tex]

[tex]b > c\ \ \ |\cdot(-1)\\\\-b < -c\ \ \ |+7,43\\\\7,43-b < 7,43-c[/tex]

[tex]b > c\ \ \ \ |+7,43\\\\b+7,42 > c+7,43[/tex]

[tex]b > c\ \ \ \ |\cdot (-7,43)\\\\-7,43b < -7,43c[/tex]
