    1) `3/4 x × 2/3 = -5/12`

    `3/4 x = -5/8`

    `x=-5/6`

    2) `3/4 x – 3/5 = 1/2`

    `3/4 x = 11/10`

    `x=22/15`

    3) `2/5 + x = 7/3`

    `x=29/15`

    4) `3/12 x + 3/4 = 1/6`

    `1/4 x=  -7/12`

    `x= -7/3`

    5) `7/4 – x = (7/8)/1`

    `x= 7/4 -7/8`

    `x=7/8`

    `1,3/4x * 2/3=-5/12`

    `<=>3/4x = -5/12 : 2/3`

    `<=>3/4x = -5/8`

    `<=>x=-5/6`

    `2, 3/4x -3/5= 1/2`

    `<=>3/4x=1/2+3/5`

    `<=>3/4x=11/10`

    `<=>x=22/15`

    `3,2/5 +x=7/3`

    `<=>x=7/3-2/5`

    `<=>x=29/15`

    `4,3/12x -3/4=1/6`

    `<=>3/12x=1/6+3/4`

    `<=>3/12x=11/12`

    `<=>x=11/3`

    `5,7/4-x=(7/8)/1`

    `<=>x=7/4-(7/8)/1`

    `<=>x=7/8`

    Vậy ………..
