As written, that is true.
(7 - 1) + 8 = 7 - (1 + 8) is not true.
8+-1= 7 x=-1
20
no x would be 0.5 because two times 0.5 is 1 ( 2x ) and then add 7 equals 8 ( plus seven equals 8 )

7-1=6
8+-1= 7 x=-1
20
The numbers are: 1 and -8
20
no x would be 0.5 because two times 0.5 is 1 ( 2x ) and then add 7 equals 8 ( plus seven equals 8 )
42
8 - 1 = 7
89
x=1
-1
6 plus 7 plus 8 equals 6 plus 8 plus 7, what property is that?That is the associative property.
