Answer 1

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.
