Find the solution of the inequality:  

Possible Answers:

Correct answer:

Explanation:

To isolate the x-variable, we will need to divide by negative four on both sides.  This is the same as multiplying negative one fourth on both sides.  

Since we have a negative in front, we will also need to switch the sign.

Simplify both sides of the equation and switch the sign.

The answer is:
