Question

solve the equation $15 = 8z + 7$.
$z = \square$

Explanation:

Step1: Subtract 7 from both sides

To isolate the term with \( z \), we subtract 7 from both sides of the equation \( 15 = 8z + 7 \). This gives us \( 15 - 7 = 8z + 7 - 7 \), which simplifies to \( 8 = 8z \).

Step2: Divide both sides by 8

Next, we divide both sides of the equation \( 8 = 8z \) by 8 to solve for \( z \). So, \( \frac{8}{8} = \frac{8z}{8} \), which simplifies to \( 1 = z \).

Answer:

\( z = 1 \)
