Solve: x + 7 = 5(3x  6)



Linear Equation 

Which of the following is an example of the transitive property?


x + 5 = x + 5 
If x = 5, then x  1 = 5  1 
If y = x  1, then x  1 = y 
If x + 5 = y and y =  1, then x + 5 = 1 

Transitive Property 

Which of the following is an example of the symmetric property?


If x + 4 = y and y = 3, then x + 4 = 3 
If y = x  3, then x  3 = y 
x + 4 = x + 4 
If x = 4, then x  3 = 4  3 

Symmetric Property 

Which property is illustrated by the following statement?
4 • (2 • 9) = (4 • 2) • 9





Which property is illustrated by the following statement?
5 + (6 + 8) = (5 + 6) + 8





Which property is illustrated by the following statement?
(4 • 8) • 9 = (8 • 4) • 9





Which property is illustrated by the following statement?
(7 + 9) + 2 = (9 + 7) + 2





Which property is illustrated in STEP 2?
5(10  9) + 9(28  7 • 4)

= 5(1) + 9(28  28) 
STEP 1 

= 5(1) + 9(0) 
STEP 2 

= 5 + 9(0) 
STEP 3 

= 5 + 0 
STEP 4 

= 5 
STEP 5
