3|x − 8| + 15 = 18

Question

3|x − 8| + 15 = 18

anonymous · Answer

First, subtract the 15 over to the other side.

3|x-8|=3

Now that you have this, divide 3 by both sides.

|x-8|=1

Do you know what to do from here?

anonymous · Answer

you change the 1 to both negative and positive and subtract 8?

anonymous · Answer

what about ones like this... |2x + 6| − 4 = 20 ?? please help that ^ really helped explaining it like that.. thank you

anonymous · Answer

Start by adding the 4 to other side.

anonymous · Answer

then divide by the 2 or just leave it ?

anonymous · Answer

Because the 2 in inside the absolute value bars, it must stay until it is alone.

anonymous · Answer

so then you divide the 24 and -24 by 6

anonymous · Answer

Okay, let's go back a step.

After you added the 4 to the 20, you ended up with this equation:

|2x + 6| = 24

From there, you may split the |2x+6| = 24 to two equations like the first.

anonymous · Answer

Just making sure you're following well.

anonymous · Answer

Now, it's easiest if you get the X value alone.

Here are your two equations:

|2x+6|=24
|2x+6|=-24

subtract the 6 to the other side in both equations.
