x > -5

x < -5

x > 5

x < 5

Answer 1

So what you want to do..is isolate the 'x' on one side...so start by adding 2 to both sides of this equation...

\[\large -3x - 2 \le 13\]
becomes
\[\large -3x \le 15\]

Now...you want to solve for 'x' not -3x ....so divide both sides of this equation by -3

**********IMPORTANT! when dividing by a negative number...you must switch the direction of the sign!*******************

so

\[\large -3x \le 15\]
becomes
\[\large x \ge -5\]

And there is your answer :)
