Which Property of Equality should be used first to solve the equation \(\frac{p}{7} - 5 = -3\) for \(p\)?

A. Addition Property of Equality
B. Subtraction Property of Equality
C. Multiplication Property of Equality
D. Division Property of Equality

Answer (2)

Well, let's solve it and see which properties we're using:
p/7 - 5 = -3
Add 5 to each side. (Addition property.)
p/7 = 2
Multiply each side by 7. (Multiplication property.)
p = 14

The first Property of Equality to use in solving the equation 7 p ​ − 5 = − 3 is the Addition Property of Equality. This involves adding 5 to both sides to isolate the term with p . Thus, the correct answer is A.
