Solution:
Analysis: We have an initial inequation; we need to isolate x in order to graph the solution.

Let's add 3.6 on both sides:

Now, let's divide by 1.6 into both sides to isolate x.

After we simplify the inequation until x is less or equal to -0.5, now we can graph the solution.
X has to be equal to or less than -0.5. That graph corresponds to the first option.
