3(x + 7) = 5x + 9 Given
3x + 21 = 5x + 9 ?
−2x + 21 = 9 ?
−2x = −12 ?
x = 6 ?


Which of the following gives the justification steps in the correct order?



a
Combine Like Terms; Distributive Property; Subtraction Property of Equality; Combine Like Terms

b
Commutative Property of Multiplication; Combine Like Terms; Addition Property of Equality; Division Property of Equality

c
Distributive Property; Combine Like Terms; Subtraction Property on Equality; Commutative Property of Addition

d
Distributive Property; Subtraction Property of Equality; Subtraction Property of Equality; Division Property of Equality

Answer 1

Answer:

d

Distributive Property; Subtraction Property of Equality; Subtraction Property of Equality; Division Property of Equality

Step-by-step explanation:

3(x + 7) = 5x + 9

3x + 21 = 5x + 9 ---> Commutative Property of Multiplication;

−2x + 21 = 9 ---> Subtraction Property of Equality

−2x = −12 ---> Subtraction Property of Equality

x = 6 ---> Division Property of Equality

Answer 2

Answer:

d

Distributive Property; Subtraction Property of Equality; Subtraction Property of Equality; Division Property of Equality
