Answer:

Step-by-step explanation:
We will need to solve the inequality:
–3x – 4 < 2
Before starting we need to understand 1 rule of inequalities. That is:

< changes to >
and
≥ change to ≤
and vice versa...
Now, let's go ahead and solve the inequality:

"x" is the set of all values that is greater than "-2". So that's the answer.
x > -2
