|6x|+3=21 solve for X (absolute value)​
Fudgin [204]

Answer:

x=3\text{ or } x=-3

Step-by-step explanation:

So we have the equation:

|6x|+3=21

First, subtract 3 from both sides:

|6x|=18

Definition of absolute value:

6x=18\text{ or } 6x=-18

Divide both sides by 6 for both equations:

x=3\text{ or } x=-3

And we're done!
