  2. `3/2 x – 70 10/11 : (131313/151515 + 131313/353535 + 131313/636363 + 131313/999999) = -5`

    `⇔ 3/2 x – 780/11 : (13/15 + 12/35 + 13/63 + 13/99) = -5`

    `⇔ 3/2 x – 780/11 : 52/33 = -5`

    `⇔ 3/2 x – 45 = -5`

    `⇔ 3/2 x  = -5 + 45`

    `⇔ 3/2 x = 40`

    `⇔ x = 80/3`

      Vậy `x=80/3`.
