z =
submit answer

Explanation:

Step1: Recognize vertical angles equality

Vertical angles are congruent, so set expressions equal:
$8z - 3 = 7z + 7$

Step2: Isolate variable z

Subtract $7z$ from both sides:
$8z - 7z - 3 = 7$

Step3: Solve for z

Add 3 to both sides:
$z = 7 + 3$

Answer:

$z = 10$
