Answer:
-3x> 24

Explanation:

Given the inequality
-x - 10 > 14 + 2x, we need to solve for "x".

We can subtract
-2x to both sides:


-2x-x - 10 > 14 + 2x-2x


-3x- 10 > 14 (This step is shown in the exercise)

Now, we can add 10 to both sides:


-3x- 10 +10> 14+10


-3x> 24 (This step is not shown in the exercise)

And finally, divide both sides by -3:


(-3x)/(-3)>(24)/(-3)


x< -8 (This is shown in the exercise)

Therefore, the missing step is:


-3x> 24
