limits. with fractions in the numerator

lim x→0 
 
(1/4)-(1/(x+4))
        x
 
Step 1 would be to get common denominators on the top so....
       (1/4)  - (1/(x+4))   =     1   -  1      = 1 (x+4)    -  1(4)
         x            x                   4     x+4       4(x+4)        (4)x+4
which is where i got stuck i got
(x+4)-4  
4(x+4)
-Which then would cancel top and bottom to where its 
(x+4)-4 -4=   -1
4(x+4)       4    
 
but i dont think thats correct please correct me and tell me where i got wrong
