  1. 2248 : [ 119 – ( x -6 ) ] = 24
    [ 119 – ( x -6 ) ] =2248: 24
     119 – ( x -6 )  =281/3
     ( x -6 )  =119- 281/3
      x -6   =76/3
      x    =76/3+6
    x=94/3
    Vậy x=94/3

  2. 2248 : [119 – (x – 6)] = 24
    119 – (x – 6) = 2248 : 24
    119 – (x – 6) = 2248/24
    119 – (x – 6) = 281/3
    x – 6 = 119 – 281/3
    x – 6 = 357/3 – 281/3
    x – 6 = 76/3
    x = 76/3 + 6
    x = 76/3 + 18/3
    x = 94/3
    Vậy x = 94/3
