Problem 16 of 7
Solve the absolute-value equation 4|x + 3| = 20 after isolating the absolute-value expression.
Using a hint is okay. It just tells the trainer to give you a little more review.

isolate absolute value before splitting.
Hidden until you reveal it.
Equation must have a coefficient or outside shift that must be undone before splitting cases.
Enter your answer
Your answer is equivalent to the expected form.

Full solution stays hidden until you ask for it.
1. Undo operations outside the absolute-value bars.
2. Once isolated, split into positive and negative cases.
3. Solve both resulting equations.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
