Consider the sequence of steps to solve the equation:

5 (x - 3) =

7x

2

Step 1 ⇒ 10 (x - 3) = 7x

Step 2 ⇒ 10x - 30 = 7x

Step 3 ⇒ 3x - 30 = 0

Step 4 ⇒ 3x = 30

Step 5 ⇒ x = 10

Identify the property of equality which gets us from Step 3 to Step 4.

A) Division Property

B) Addition Property

C) Subtraction Property

D) Multiplication Property
