Answer:
The correct answer is Option A: Multiplication Property of Equality
Step-by-step explanation:
Given equation is:

The given equation is a linear equation in one variable. Different equality properties are used to solve equations like these.
First of all the denominator with 1/5x has to be eliminated for which the whole equation will be multiplied by 5

This property is called multiplication property of equality.
Hence,
The correct answer is Option A: Multiplication Property of Equality
