Question

What is the solution for -10 < x - 9? x > -19 x < -19 x > -1 x < -1

Answer 1

Option C: x > -1 is the right answer.

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
