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
