Cannot be determined
Step-by-step explanation:
You cannot assume the function travels down infinitely, because the function is not given to you. The graph could go up down left or right for all you know, you just cannot see it.
Start by dividing both sides by 2:
5x + 6 = 5x + 6
Simplify:
0 = 0
This indicates infinite solutions:
x = All real numbers.
