Answer:
Anything
Step-by-step explanation:
5n - 10 = 5n - 10
It doesn't matter what you put in for n, the equality can never be anything but an equality.
Suppose n = 10,000,000
Then 5*10,000,000 - 10 = 5*10,000,000
n = (-∞,∞) or all real numbers
To solve distribute the 5,
5(n–2)=5n–10
add 10 to both side
5n = 5n
divide by 5
n=n
the equation is identical
you can say n solutions are all numbers from (-∞,∞)
