Question

This is a solution to 2p - 30 = -4p + 6. Justify step 3.

1. 2p - 30 = -4p + 6 (Reason: Given)

2. 6p - 30 = 6 (Reason: Addition Property of Equality)

3. 6p = 36 (Reason: ??)

4. p = 6 (Reason: Division Property of Equality)

A) Subtraction Property of Equality
B) Reflexive Property of Equality
C) Transitive Property of Equality
D) Addition Property of Equality

Answer 1

To get from step 2 to step 3, you would just have to add 6 to both sides of the equation. Then, you get 6p = 36. Thus, I think that it would be the addition property of equality.
