To determine if \( z = 2 \) is a solution to the equation \( 8 = 3z \), we can substitute \( z \) with 2 and check if the equation holds true.
Starting with the equation:
\[ 8 = 3z \]
Substituting \( z = 2 \):
\[ 8 = 3(2) \]
Calculating the right side:
\[ 8 = 6 \]
Since \( 8 \) does not equal \( 6 \), \( z = 2 \) is not a solution to the equation \( 8 = 3z \).
