Answer:No friend is wrong
Step-by-step explanation: you actually get two answers. After you isolate the absolute value then you take the positive and negative number of what it's set equal too.
|3x + 8| - 9 = -5 add 9 to isolate the absolute value
|3x + 8| = 4
Now set two equations because the abosulte value has two answers.
|3x + 8| = 4. and |3x + 8| = -4
Solve these by removing the absolute value bars.
3x = -4. 3x = -12
x = -4/3. X = -4
