Answer:
D. Subtraction and division property
Explanation:
The Subtraction Property of Equality states that if the same quantity is subtracted from both sides of an equation, the two sides remain equal.
- If a = b, then a - c = b - c.
Therefore, the first property of equality used is the subtraction property since the first step in the solution was to subtract 5 from both sides of the equation:

The Division Property of Equality states that if both sides of an equation are divided by the same non-zero quantity, the two sides remain equal.
- If a = b, and c ≠ 0, then a ÷ c = b ÷ c
Therefore, the second property of equality used is the division property since the second step in the solution was to divide both sides of the equation by 6:
