Explanation:

Step 1: Define


\displaystyle 3a + 2 > (3a - 6)/(3)

Step 2: Solve for a

  1. [Multiplication Property of Equality] Multiply 3 on both sides:
    \displaystyle 3(3a + 2) > 3a - 6
  2. [Distributive Property] Distribute 3:
    \displaystyle 9a + 6 > 3a - 6
  3. [Subtraction Property of Equality] Subtract 3a on both sides:
    \displaystyle 6a + 6 > -6
  4. [Subtraction Property of Equality] Subtract 6 on both sides:
    \displaystyle 6a > -12
  5. [Division Property of Equality] Divide 6 on both sides:
    \displaystyle a > -2
