  1. Giải đáp + Lời giải và giải thích chi tiết:
    Bạn tham khảo~~
    9/6 xx (x – 5/3) + 3/2 xx 5/3 = 3
    3/2 xx (x – 5/3) + 3/2 xx 5/3 = 3
    3/2 xx (x – 5/3 + 5/3)            = 3
    x – 5/3 + 5/3                         = 3 : 3/2
    x – 5/3 + 5/3                         = 2
    x – 5/3                                   = 2 – 5/3
    x – 5/3                                   = 1/3
    x                                            = 1/3 + 5/3
    x                                            = 2

  2. 9/6 xx (x – 5/3) + 3/2 xx 5/3 = 3
    9/6 xx (x – 5/3) + 5/2 = 3
    9/6 xx (x – 5/3) = 3 – 5/2
    9/6 xx (x – 5/3) = 1/2
    (x – 5/3) = 1/2 : 9/6
    x – 5/3 = 1/3
    x = 1/3 + 5/3
    x = 2
    Vậy: x = 2
