219-(x+1)=199

       x+1 = 219 - 199

       x+1  = 100

       x      = 100 - 1

       x      = 99

Vậy x = 99

219-1=218

Số đó lả : 218

219-(X+1) =119

        X+1=219-119

         X+1=100

         X=100-1=99

-219 - ( -190 ) = 29 ( tuổi )

-219 - (-190) = 29 (tuổi)

=> Ối chà =)) Sống thọ quá ha ^^

Tuổi thọ của bác học Ac-si-mét là: 

    - 190 - ( - 219) = 29 (tuổi)
