it is 7
6 and 1 out of2

-7+8=1
6/12 + 8/12 = 6+8/12 = 14/12 = 7/6 = 11/6
it is 7
6-2 = 4 8+7 ≠3 9+5 = 14
6 plus 7 plus 8 equals 6 plus 8 plus 7, what property is that?That is the associative property.
If you mean: 6*(7+8)*(6+7)+8 then it works out as 1178

7x+8=2 .....-8..-8 7x=-6 7x/7=6/7 x=6/7 In conclusion, 7(6/7)+8=2 I'm sure you meant: x = - (6/7) or -6/7 (not 6/7).
It is the same as: 6/8+7/8 = 13/8 or 1 and 5/8
144
8 plus 7 is 15. 15 plus 6 is 21. :)
-7+8=1
6/12 + 8/12 = 6+8/12 = 14/12 = 7/6 = 11/6
