Remove the absolute value term. This creates a ± on the right-hand side of the equation because |x|=±x.
3w+6=±(9)
Set up the
3w+6=9
Move all terms not containing w to the right-hand side of the equation.
3w=3
Divide each term in the equation by 3.
w=1
Set up the − portion of the ± solution.
3w+6=−(9)
Simplify.
3w+6=−9
Since 6 does not contain the variable to solve for, move it to the right-hand side of the equation by subtracting 6 from both sides.
3w=−6−9
Subtract 9 from −6 to get −15.
3w=−15
Divide each term in the equation by 3.
w=−5
w=1,−5
