Question

to solve the inequality, start by finding the value of z that makes 9z + 15 = 51 true.
9z + 15 < 51
9z + 15 = 51
z =

Explanation:

Step1: Subtract 15 from both sides

To isolate the term with \( z \), we subtract 15 from both sides of the equation \( 9z + 15 = 51 \). This gives us \( 9z + 15 - 15 = 51 - 15 \), which simplifies to \( 9z = 36 \).

Step2: Divide both sides by 9

To solve for \( z \), we divide both sides of the equation \( 9z = 36 \) by 9. So, \( \frac{9z}{9} = \frac{36}{9} \), which simplifies to \( z = 4 \).

Answer:

\( z = 4 \)
