    ( x – 2/3) xx 3 = 3/4
    ( x – 2/3) = 3/4 : 3
    ( x – 2/3) = 3/4 xx 1/3
    x – 2/3 = 1/4
    x = 1/4 + 2/3
    x = 3/12 + 8/12
    x=11/12
    Vậy x = 11/12
    4 1/2 – 1/2xx x = 1/3
    9/2 – 1/2 xx x = 1/3
    1/2 xx x = 9/2 – 1/3
    1/2 xx x = 27/6- 2/6
    1/2 xx x = 25/6
    x = 25/6 : 1/2
    x = 25/6 xx 2/1
    x = 25/3
    Vậy x = 25/3
    1/5 xx ( 11 – x xx 3) = 1
    ( 11 – x xx 3) = 1 : 1/5
    (11 – x xx 3) = 1 xx 5
    11 – x xx 3 = 5
    x xx 3 = 11 – 5
    x xx 3 = 6
    x = 6 : 3
    x = 2
    Vậy x = 2

    (x-2/3)xx3=3/4
