Answer: Division property of equality

Explanation:

The division property of equality says that if we divide both sides of an equation by the same nonzero number, the sides remain equal.

Therefore if we have equation
3x=6 , then we divide both sides by 3 .

So by division property of equality, we get

$\ x=(6)/(3)\\\Rightarrow\ x=2$

Hence, Division property of equality justifies If 3x = 6, then x = 2.
