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: \[ 12n - 3 \]

To simplify the expression \(3(5n - 1) - 3n\), we can follow these steps:

Distribute the \(3\) in the first term: \[ 3(5n) - 3(1) = 15n - 3 \]
Now, substitute this back into the expression: \[ 15n - 3 - 3n \]
Combine the \(n\) terms: \[ (15n - 3n) - 3 = 12n - 3 \]

So, the simplified expression is: \[ 12n - 3 \]
