Answer:
Step-by-step explanation:
Step 1: add 4 to both sides, obtaining 2|x+5| = 10
Step 2: Divide both sides by 2 to isolate |x + 5|: |x + 5| = 5
Step 3: Rewrite this result as two separate equations:
x + 5 = 5, so x = 0, and
-(x + 5) = 5, which simplifies to -x - 5 = 5, or -x = 10, or x = -10
The solution set is {0, -10}
