To simplify the expression \(3(5n - 1) - 3n\), we can follow these steps:
1. Distribute the \(3\) in the first term:
\[
3(5n) - 3(1) = 15n - 3
\]
2. Now, substitute this back into the expression:
\[
15n - 3 - 3n
\]
3. Combine the \(n\) terms:
\[
(15n - 3n) - 3 = 12n - 3
\]
So, the simplified expression is:
\[
12n - 3
\]
