Question

5(2x + 4) = 50 (Given) 10x + 20 = 50 (Distributive Property) 10x = 30 (?) x = 3 (Division Property) Fill in the missing reason for the argument shown. A) multiplication B) division property C) transitive property D) subtraction property

Answer 1

D because 20 was taken to the other side and was subtracted from 50 which makes 30

Answer 2

We go from 10x+20 = 50 to 10x = 30 after we subtract 20 from both sides. So we use the subtraction property (of equality).

Answer: Choice D
