Problem 108 of 7
Show that the original system 2x + y = 7, x - y = -1 and transformed system 3x = 6, x - y = -1 have the same ordered-pair solution.
Using a hint is okay. It just tells the trainer to give you a little more review.
Hidden until you reveal it.
solve or verify both systems and compare solution sets.
Hidden until you reveal it.
Systems must be equivalent by a valid elimination transformation and have a checkable solution.

Your answer is equivalent to the expected form.
Walkthrough
Full solution stays hidden until you ask for it.
1. Find or use the claimed solution.
2. Substitute the ordered pair into every equation in both systems.
3. If all are true, the systems share that solution.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
