Ответ:

[tex]a-9 > b-9\\\\\frac{a}{6} > \frac{b}{6}\\\\5a > 5b[/tex]

Объяснение:

[tex]a > b\ \ \ |-9\\\\a-9 > b-9\\\\\\a > b\ \ \ \ |\cdot (-5)\\\\-5a < -5b\\\\\\a > b\ \ \ |:6\\\\\frac{a}{6} > \frac{b}{6}\\\\\\a > b\ \ \ \ |\cdot(-1)\\\\-a < -b\ \ \ |+14\\\\14-a < 14-b\\\\\\a > b\ \ \ |\cdot 5\\\\5a > 5b[/tex]
