Let’s check out your problem:

Haley solved the equation $25 + 3n - 12 = 13 + 7n - 4n$. Here are her last two steps:$\newline$$13 + 3n = 13 + 3n$$\newline$$13 = 13$$\newline$Which statement is true about the equation?$\newline$(A)The solution is $n = 13$.$\newline$(B)There is no solution because $13 = 13$ is a true equation.$\newline$(C)There are infinitely many solutions because $13 = 13$ is a true equation.$\newline$(D)The solution is $(13, 13)$.
