To solve the equation \(3z + 8 = 20\), we need to isolate \(z\).

  1. Subtract 8 from both sides: \[ 3z + 8 - 8 = 20 - 8 \] This simplifies to: \[ 3z = 12 \]

  2. Next, divide both sides by 3: \[ z = \frac{12}{3} \] This simplifies to: \[ z = 4 \]

Since 4 is not one of the options provided (44, 88, 1010, 1313), it appears there may be a misunderstanding in the options. If you are asking for the value of \(z\) in the equation given, it is 4.

Please confirm if you meant to ask for something different or if there was an error with the options listed.
