Answer:
Option C: x > -1 is the right answer.
Step-by-step explanation:
Given that:
-10 < x - 9--------- eq1
Adding 9 on both sides:
-10 + 9< x - 9 + 9
On left side:
Subtracting positive digit from negative one (greater) will give answer in negative. (-10+9 =-1)
On right side:
Negative 9 will be cancelled by positive 9 and simplified as follows:
-1 < x
OR
x > -1
