Question

score: 3/5 penalty: none question solve. 5(z - 4) = 20 answer attempt 1 out of 2 z =

Explanation:

Step1: Divide both sides by 5

To isolate the term with \( z \), we divide both sides of the equation \( 5(z - 4)=20 \) by 5. This gives us \( \frac{5(z - 4)}{5}=\frac{20}{5} \), which simplifies to \( z - 4 = 4 \).

Step2: Add 4 to both sides

To solve for \( z \), we add 4 to both sides of the equation \( z - 4 = 4 \). So, \( z - 4 + 4 = 4 + 4 \), which simplifies to \( z = 8 \).

Answer:

\( z = 8 \)
