@myininaya what do you mean

myininaya · Answer

I was just asking the person who gave you the answer (the answer I deleted) to explain it.

myininaya · Answer

I guess they do not want to since they haven't replied.
I will help.
First get the absolute value part by itself. It is being multiplied by -3, so divide both sides by -3.
Let me know what you get when doing this first step.

$$\left| 2x+6 \right|=\frac{ -12 }{-3 }=4,2x+6=\pm 4$$
solve the two values of x.
