Answer: Division property of equality
Explanation:
If we have equation 3x=6, then we divide both sides by 3 , such that the sides remain same.
So by division property of equality, we get

Hence, Division property of equality justifies that if 3x = 6, then x = 2.
- The division property of equality says that if we divide both sides of an equation by the same nonzero number, the sides remain equal.
