Question 29792
(x/5)-(4/5)=9-(2x/-9)-(4/-9)
(x-4)/5 = 9+(2x/9)+(4/9)  (using (-1)/(-1) =+1 )
(x-4)/5 = (9X9+2x+4)/9 ----(2)   
Multiplying by 5X9 through out 
9(x-4)= 5X(81+2x+4)
9x-36 = 405+10x+20
9x-10x = (405+20+36)
-x= 461
That is x = -461
Verification:  Putting x =-461 in (2)
LHS = (x-4)/5 = [-461-4]/5 =-465/5 =-93
RHS = (81-922+4)/9 = (-922+85)/9 = -837/9 = -93 =LHS
Therefore our value is correct
