Answer:
Answer = no solution
Step-by-step explanation
Step 1: Add all the like-terms together
1. 2 + 7x = 7x - 5
Step 2: Subtract 7x from both sides
2. 2 + 7x - 7x = -5 → 2 ≠ -5
Because all the variables were canceled with a resulting false statement, there is no solution to this system.
Hope this helps :)
