To determine if \( k = 2 \) is a solution to the equation \( 3 - k = 0 \), we can substitute \( k \) with 2.
Starting with the equation:
\[ 3 - k = 0 \]
Substituting \( k = 2 \):
\[ 3 - 2 = 0 \]
Simplifying the left side:
\[ 1 = 0 \]
This statement is false. Therefore, \( k = 2 \) is not a solution to the equation.
The answer is no.
