Question

Given: x – 2(x + 2 + 2x) = 10 + 2x Prove: x = –2 Mathematical Statement Justification x – 2(x + 2 + 2x) = 10 + 2x Given x – 2(x + 2x + 2) = 10 + 2x Commutative Property of Addition x – 2(3x + 2) = 10 + 2x Combine Like Terms x – 6x – 4 = 10 + 2x Distributive Property – 5x – 4 = 10 + 2x – 7x – 4 = 10 – 7x = 14 x = –2 Division Property of Equality What are the missing justification steps, in order? Answer Distributive Property, Addition Property of Equality, Subtraction Property of Equality Combine Like Terms, Subtraction Property of Equality, Additio

Answer 1

Can you be a little more clear/specific with your question? I want to help you but all I'm seeing is a lot of words.

Answer 2

That's all that is there -_________- I don't understand at all. it's just a big paragraph, do you want me to put the answer choices up?

Answer 3

Associative Property of Addition

Subtraction Property of Equality

Addition Property of Equality

Commutative Property of Subtraction


I was thinking the third one, because it looks like it equaled it out. But honestly I am completely lost.
