x+7+x+3=10                    b) Substitution Property
2x+10=100                       c) Simplify
2x=90                               d) ?_______

Does any one know what property A and D is? Here are the choices:

1. Angle Addition Postulate; Addition Property of Equality
2. Angle Addition Postulate; Subtraction Property of Equality
3. Protractor Postulate; Addition Property of Equality
4. Protractor Postulate; Subtraction Property of Equality

My thought was that it is 3

It wouldn't be 3. When going from steps C to D, you're not adding. You're subtracting 10 from both sides.

So we can eliminate 1 and 3 as possible answer choices.
