To simplify the expression \(3(4x + 1) - 1 - x\), follow these steps:
-
Distribute the \(3\) into the parentheses:
\(3(4x) + 3(1) = 12x + 3\). -
Now substitute this back into the expression:
\(12x + 3 - 1 - x\). -
Combine like terms:
\(12x - x + 3 - 1 = 11x + 2\).
So, the simplified expression is:
\[
\boxed{11x + 2}
\]
