Question

Select the property that allows the left member of the equation to be changed to the right member.

Answer 1

8 + 0 = 8: identity- addition (any number + 0= that number) 
a(b + c) = ab + ac: distributive (multiplying a on the left-hand side of the equation by the numbers in parenthesis gives you the right-hand side of the equation) 
b + a = a + b: commutative- addition (numbers can be added in any order and still produce the same answer) 
If 2 = x, then x = 2: symmetric (if a = b then b = a) 
x(10) to be written 10x: commutative- multiplication (numbers can be multiplied in any order and still produce the same result)

Answer 2

Commutative property
