Answer 1

$- 10 < x - 9$
ANSWER
$x > - 1$

Answer 2

Answer:

$\LARGE \boxed{x>-1}$

Step-by-step explanation:

First switch sides.

$\displaystyle x-9>10$

Add by 9 from both sides.

$\displaystyle x-9+9>-10+9$

Simplify, to find the answer.

$\displaystyle -10+9=-1$

$\LARGE \boxed{x>-1}$, which is our answer.
