The solution set of 18 - 3n + 2 = n + 20 - 4n is all reals.

18 - 3n + 2 = n + 20 - 4n

-3n + 20 = -3n + 20

-3n + 3n = 20 - 20

0 = 0

So there are infinite solution for the equation.

18 - 3n + 2 = n + 20 - 4n

-3n + 20 = -3n + 20

-3n + 3n = 20 - 20

0 = 0

So there are infinite solution for the equation.
