...we have to flip around the "greater than/ less than" Pac Man thingies.
First, let's just break this puppy into pieces.
We start with negative 2 is less than or equal to 3x plus 1.
Subtract 1 from both sides to get negative 3 is less than or equal to 3x.
Divide both sides by 3 and we have -1 is less than or equal to x.
Great; that lets us cross off a few answers from the potentials sheet.
Now for the next part. We have 3x plus 1 is less than 2.
Subtract 1 from both sides and we have 3x is less than 1.
Divide both sides by 3 to get x is less than 1 third.
And our answer is E.
