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...
