2) 5x + 15 + 9 = 59 2)
3) 5x + 24 = 59 3)
4) 5x + 0 = 35 4)
5) 5x = 35 5)
6) x = 7 6)

Choices:

A. Reflexive Property
B. Symmetric Property
C. Transitive Property
D. Addition Property of Equality
E. Subtraction Property of Equality
F. Multiplication Property of Equality
G. Division Property of Equality
H. Substitution Property

Answer 19

@chicagoblkhaks
I am not doling out answers here.
I have to look at the entire set of steps to be supported.
I am not saying that this is correct.


Given: 5 (x + 3) + 9 = 59
Prove: x = 7

Statements Reasons
-------------------------
1) 5(x + 3) + 9 = 59 GIVEN

2) 5x + 15 + 9 = 59 DISTRIBUTIVE PROPERTY

3) 5x + 24 = 59 DEFINITION OF ADDITION (15 + 9 = 24)

4) 5x + 0 = 35 SUBTRACTION PROPERTY OF EQUALITY

5) 5x = 35 ADDITIVE IDENTITY

6) x = 7 DIVISION PROPERTY OF EQUALITY

Answer 20

@mathstudent55 causes me to think that this:

3) 5x + 24 = 59 DEFINITION OF ADDITION (15 + 9 = 24)

should read:

3) 5x + 24 = 59 SUBSTITUTION PROPERTY (24 substituted for 15 + 9)
