Consider the sequence of steps to solve the equation:
5(x - 3) = 7x2
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.

The property of equality used to get from Step 3 to Step 4 is the addition property of equality. This property allows us to add the same value to both sides of an equation, in this case adding 30 to both sides.

I apologize for the confusion. The property used is the addition property of equality.
