Answer:
Infinite solutions
Step-by-step explanation:
Distribute the 2 to (n - 1), and distribute the 2 to (3n - 1), like so:
2(n - 1) + 4n = 2(3n - 1)
2n - 2 + 4n = 6n - 2
Add like terms (2n and 4n):
6n - 2 = 6n - 2
Subtract 6n from both sides:
-2 = -2
Since we ended up with the same term on both sides, we can't do anything else, meaning this equation has infinite solutions.
