Answer:

x=-5,x=+5

Step-by-step explanation:

The question says 15=|3x|

So to solve this question we will have to eliminate the || from 3x and to do so we will transfer it to 15... when it gets to 15 it will be + or - 15

So let's solve

Starting from +15=3x

Make x the subject of formula

x=+5

Let's move to the -15=3x

Make x the subject of formula

x=-5

Therefore x is either+5 or -5

That's the final answer for the given question...

I believe this will help you to understand it better
