Question

solve the given equation for z and write the correct answer. 4z + 9 = 29

Explanation:

Step1: Subtract 9 from both sides

To isolate the term with \( z \), we subtract 9 from both sides of the equation \( 4z + 9 = 29 \). This gives us \( 4z + 9 - 9 = 29 - 9 \), which simplifies to \( 4z = 20 \).

Step2: Divide both sides by 4

To solve for \( z \), we divide both sides of the equation \( 4z = 20 \) by 4. So, \( \frac{4z}{4} = \frac{20}{4} \), which simplifies to \( z = 5 \).

Answer:

\( z = 5 \)
