Answer:
- Infinitely many solutions
Step-by-step explanation:
<u>Given system:</u>
<u>Divide the first equation by 2 and rearrange:</u>
- 2y/2 = 14/2 - 2x/2
- y = 7 - x
- y = -x + 7
We got the same equation with the second one. It means we have two of the same lines overlapping.
This gives us infinitely many solutions.
