Answer:
e = 6
Step-by-step explanation:
Step 1: Write equation
-2(8 - e) = 2 - e
Step 2: Solve for <em>e</em>
- Distribute -2: -16 + 2e = 2 - e
- Add e to both sides: -16 + 3e = 2
- Add 16 to both sides: 3e = 18
- Divide both sides by 3: e = 6
Step 3: Check
<em>Plug in e to verify it's a solution.</em>
-2(8 - 6) = 2 - 6
-2(2) = -4
-4 = -4
