Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify.</em>
42 = -7(z - 3)
<u>Step 2: Solve for </u><em><u>z</u></em>
- [Distributive Property] Distribute -7: 42 = -7z + 21
- [Subtraction Property of Equality] Subtract 21 on both sides: 21 = -7z
- [Division Property of Equality] Divide -7 on both sides: -3 = z
- Rewrite: z = -3
