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
