    To solve for z in the equation 4z + 8 = 20, we need to isolate z on one side of the equation. Here’s how we can do that:

    1. Start with the equation: 4z + 8 = 20

    2. Subtract 8 from both sides of the equation to isolate the term with z:
      4z + 8 – 8 = 20 – 8
      4z = 12

    3. Divide both sides of the equation by 4 to solve for z:
      (4z)/4 = 12/4
      z = 3

    Therefore, the solution to the equation 4z + 8 = 20 is z = 3.

    • Isolate the term with <math xmlns=”http://www.w3.org/1998/Math/MathML”><semantics><mrow><mi>z</mi></mrow><annotation encoding=”application/x-tex”>z</annotation></semantics></math>z:

      Subtract 8 from both sides of the equation:
