Step-by-step explanation:
<u>Step 1: Define</u>
2/3(6h - 9) = 6
<u>Step 2: Solve for </u><em><u>h</u></em>
- [Division Property of Equality] Divide 2/3 on both sides: 6h - 9 = 9
- [Addition Property of Equality] Add 9 on both sides: 6h = 18
- [Division Property of Equality] Divide 6 on both sides: h = 3
