Properties of Equality
1) 12 X 2 = 24 so
(12 X 2)/6 = 24/6
2) 19-4=15 so
(19-4)+6 = 15+6
3) 21+7=28 so
(21+7)-18 = 28-18
what properties are they looking for?
(Broken Link Removed)
First: division property
second: addition property
third: subtraction property
They are only demonstrating that you can add, subtract or multiply both sides of an equation by equal amounts, and still end up with a valid equation.
It was too obvious! I have been out of this for a while, my other daughter is 25! Thank you.
