Use brackets to make things clearer.
I think you mean:
(4x + 5)/(x+5) - (5x + 6)/(x+5)
step 1:
factor out the common denominator:
[(4x + 5) - (5x + 6) ] / (x + 5)
step 2, perform the operations inside the square brackets:
[ 4x + 5 - 5x - 6 ] = [ (4-5)x + (5-6) ] = [ -x - 1 ] = [ -(x+1) ]
step 3: put everything back together
-(x+1)/(x+5)
It cannot be reduced any further.

Will assume that question is actually incorrect and SHOULD be shown as :-
( 4x + 5 ) / ( x + 5 ) - ( 5x + 6 ) / ( x + 5 )
4x + 5 - 5x - 6
--------------------
( x + 5 )
- x - 1
-----------
x + 5
- ( x + 1 )
---------------
x + 5
( 4x + 5 ) / ( x + 5 ) - ( 5x + 6 ) / ( x + 5 )
4x + 5 - 5x - 6
--------------------
( x + 5 )
- x - 1
-----------
x + 5
- ( x + 1 )
---------------
x + 5
