-3x > 9
Let us solve if -3x = 9
-3x = 9
x = 9/-3
x = -3
So to make the equation -3x > 9
x should be less than -3
x< -3 ===> the correct answer

C
You have to divide by -1 and turn sign around.
3x < -9
Then divide by 3 so x < -3

-3. When you divide a number by negative for inequalities, you need to reverse the sign for it goes to the exact opposite with respect to zero.
