Simplify completely: ( x + 7 )/( x - 7 ) divided by (x2 - 49 )/( 7 - x )

------------
:
We can rewrite (7-x) to -1(x-7) and factor (x^2-49), (difference of squares)
------------
:
Cancel out the (x-7)'s in the dividing fraction
------------
:
Invert the dividing fraction and multiply
* - = -; canceled (x+7)'s
