  1. Giải đáp+Lời giải và giải thích chi tiết:
    46 – ( 11 – 2 . X ) : 3 – 6 = 39
    46 – ( 11 – 2 . X ) : 3 = 39+6
    46 – ( 11 – 2 . X ) : 3 = 45
    11 – 2 . X : 3 = 46 – 45
    11 – 2 . X : 3 = 1
    11 – 2 . X = 1 . 3
    11 – 2 . X = 3
    2 . X = 11-3
    2 . X = 8
    X = 8 : 2
    X = 4

  2. 46 – ( 11 – 2 × x ) : 3 – 6 = 39
    46 – ( 11 – 2 × x ) : 3 = 39 + 6
    46 – ( 11 – 2 × x ) : 3 = 45
    ( 11 – 2 × x ) : 3 = 46 – 45
    ( 11 – 2 × x ) : 3 =1
    11 – 2 × x = 1 × 3
    11 – 2 × x = 3
    2 × x = 11 – 3
    2 × x = 8
          x = 8 : 2
          x = 4
    Vậy x = 4
