5|x+3|-4-8|x+3|=-4
Subtract 8|x+3| from both sides.
-3|x+3|-4=-4
Combine 5|x+3| and -8|x+3| to get -3|x+3|.
-3|x+3|=-4+4
Add 4 to both sides.
-3|x+3|=0
Add -4 and 4 to get 0.
|x+3|=0
Divide both sides by -3. Zero divided by any non-zero number gives zero.
x+3=0
Use the definition of absolute value.
x=-3
Subtract 3 from both sides of the equation.
