entered :
-|3x-9|+2=-4
Step by step solution :
STEP
1
:
Rearrange this Absolute Value Equation
Absolute value equalitiy entered
-|3x-9|+2 = -4
Another term is moved / added to the right hand side.
To make the absolute value term positive, both sides are multiplied by (-1).
|3x-9| = 6
STEP
2
:
Clear the Absolute Value Bars
Clear the absolute-value bars by splitting the equation into its two cases, one for the Positive case and the other for the Negative case.
The Absolute Value term is |3x-9|
For the Negative case we'll use -(3x-9)
For the Positive case we'll use (3x-9)
STEP
3
:
Solve the Negative Case
-(3x-9) = 6
Multiply
-3x+9 = 6
Rearrange and Add up
-3x = -3
Divide both sides by 3
-x = -1
Multiply both sides by (-1)
x = 1
Which is the solution for the Negative Case
STEP
4
:
Solve the Positive Case
(3x-9) = 6
Rearrange and Add up
3x = 15
Divide both sides by 3
x = 5
Which is the solution for the Positive Case
STEP
5
:
Wrap up the solution
x=1
x=5
I hope this help you
