    Giải đáp:
    (x+3)/327 + (x+3)/326 + (x+4)/325 + (x+5)/324 + (x+349)/5 = 0
    -> (x+3)/327 + (x+3)/326 + (x+4)/325 + (x+5)/324 + (x+349)/5 + 4 – 4= 0
    -> (x+3)/327 +1 + (x+3)/326 +1 + (x+4)/325 +1 + (x+5)/324 +1 + [(x+349)/5 – 4] = 0
    -> (x+329)/327 + (x+329)/326 + (x+329)/325 + (x+329)/324 + (x+329)/5 = 0
    -> (x+329).(1/327 + 1/326 + 1/325 + 1/324 + 1/5 ) = 0
    Do  (1/327 + 1/326 + 1/325 + 1/324 + 1/5) \ne 0
    -> x+329 = 0
    -> x = -329
    Vậy x=-329
    Go od luck!
