Question 1154604: 1. This one was solved using substitution:
x + y = 2
4y = -4x + 8
Answer: x = 2−y
and
2. This one was solved using elimination:
x + y = 2
4y = -4x + 8
Answer: (x, 2 - x)
The question I have is "what does this mean for the solution?"
Thank you

The question I have is "what does this mean for the solution?"
--------
In both cases, the equations are dependent. It's the same equation twice.
---> infinite # of solutions, no unique solution.
