  1. x xx 7 + x : 1/2 + x xx 1 = 5/7
    x xx 7 + x xx 2 + x xx 1 = 5/7
    x xx (7 + 2 + 1) = 5/7
    x xx 10 = 5/7
    x = 5/7 : 10
    x = 5/7 xx 1/(10)
    x = 1/(14)
    Vậy x=1/(14)
     

  2. Giải đáp:
    x×7 + x:1/2 + x×1 = 5/7
    x×7 + x × 2 + x×1 = 5/7
    x × (7 + 2 + 1) = 5/7
    x × 10 = 5/71
    x = 5/7 : 10
    x = 1/14
    Vậy x = 1/14
