Answer:

The property used "Multiplication property of equality"

A is correct

Step-by-step explanation:

Given: If x = 4, then 5x = 20

We are given an equation x=4

We need to make 5x=20

The coefficient of x in first equation is 1 but in second equation is 5.

So, If we multiply both sides by 5 in x=4 equation

[tex]x=4[/tex]

Multiplication property of equality

[tex]5\cdot x=5\cdot 4[/tex]

[tex]5x=20[/tex]

Hence, The property used "Multiplication property of equality"
