Answer:

z = 1/2

Step-by-step explanation:

Step 1: Write equation

-3z - 1 = 1 - 7z

Step 2: Solve for <em>x</em>

  1. Add 7z to both sides: 4z - 1 = 1
  2. Add 1 to both sides: 4z = 2
  3. Divide both sides 4: z = 1/2

Step 3: Check

<em>Plug in z to verify it's a solution.</em>

-3(1/2) - 1 = 1 - 7(1/2)

-3/2 - 1 = 1 - 7/2

-5/2 = -5/2
