    Đáp án:dưới nha

    Giải thích các bước giải:

    a) 10/3+x= -5

       x= -5-10/3=-25/3

    b) x+1/2=1/3-(-1/4)

    x+1/2=7/12

    x=7/12-1/2=1/12

    c)4/9.x-1/2=2/7

    4/9.x=2/7+1/2=11/14

    x=11/14:4/9=99/56

    d)10/9:x+7/12= -2/3

    10/9:x=-2/3-7/12=-5/4

    x=10/9:9-5/4)

    x= -8/9

    Đáp án:

    Giải thích các bước giải:

    a, x= -5-$\frac{10}{3}$= -25/3

    b, x= 1/3+1/4-1/2=1/12

    c, 4/9x=2/7+1/2=11/14

    x=11/14:4/9=11/14.9/4=99/56

    d, 10/9:x= -2/3-7/12=-5/4

    x= 10/9:(-5/4)=10/9.(-4/5)=-8/9
