    a) `2/3 x = -4/27`

    `<=> x = -4/27 : 2/3`

    `<=> x = -2/9`

    b) `-8/5 x = 16/15`

    `<=> x = 16/15 : (-8/5)`

    `<=> x = -2/3`

    c) `1/3 + 1/2 😡 = -4`

    `<=> 1/2 : x = -4 – 1/3`

    `<=> 1/2 : x = -13/3`

    `<=> x = 1/2 : (-13/3)`

    `<=> x = -3/26`

    d) `3/4 + 1/4 : x= 2/5`

    `<=> 1/4 : x= 2/5 – 3/4`

    `<=> 1/4 : x = -7/20`

    `<=> x= 1/4 : (-7/20)`

    `<=> x= -5/7`

    a)2/3 x =-4/27

               x=-4/27:2/3

               x=-2/9

    b)-8/5 x =16/15

                 x=16/15:(-8/5)

                 x=-2/3

    c)1/3+1/2:x =-4

                     1/2:x=-4-1/3

                      1/2:x=-13/3

                            x=1/2:(-13/3)

                            x=-3/26

    d)3/4 + 1/4:x = 2/5

                   1/4:x=2/5-3/4

                   1/4:x=-7/20

                         x=1/4:(-7/20)

                         x=-5/7
