If \\(n=4\\), what is the value of \\(3n-2\\)?

Answer and explanation

Correct answer: 10

Substituting \\(n=4\\) into the expression gives \\(3n-2=3\\times4-2=12-2=10\\). Therefore, 10 is correct. The value 12 results from stopping at \\(3\\times4\\) without subtracting 2. In such questions, substitute the variable first, then perform multiplication before subtraction.
