Answer:
X= 5, -9
Step-by-step explanation:
1. Move all terms not containing |x+2| to the right side of the equation.
3|x+2|=21
2. Divide each term in 3|x+2|=21 by 3 and simplify
|x+2|=7
3. Remove the absolute value term. This creates a ± on the right side of the equation because |x| = ±x
x+2= ±7
4. The complete solution is the result of both the positive and negative portions of the solution
x= 5, -9
