    Giải đáp + Lời giải và giải thích chi tiết:
    a) 1569 – x = 230
                   x = 1569 – 230
                   x = 1339.
    b) 1456 + x = 146 + 123
        1456 + x = 269
                    x = 269 – 1456
                    x = – 1187
    c) 102 : x = 51
                x = 102 : 51
                x = 2
    ~Xin hay nhất ạ ! ~

    a) 1569 – x = 230
    x = 1569 – 230
    x = 1339
    $\text{Vậy x = 1339}$
    b) 1456 + x = 146 + 123
    1456 + x = 269
    x = 269 – 1456
    x = – 1187
    $\text{Vậy x = – 1187}$
    c) 102 : x = 51
    x = 102 : 51
    x = 2
    $\text{Vậy x = 2}$
