Answer:
z = 1/2
Step-by-step explanation:
Step 1: Write equation
-3z - 1 = 1 - 7z
Step 2: Solve for x
- Add 7z to both sides: 4z - 1 = 1
- Add 1 to both sides: 4z = 2
- Divide both sides 4: z = 1/2
Step 3: Check
Plug in z to verify it's a solution.
-3(1/2) - 1 = 1 - 7(1/2)
-3/2 - 1 = 1 - 7/2
-5/2 = -5/2
