1. `5/9 – (5/6 -x) = -8/18`

   => ` 5/9 – 5/6 + x = -8/18`

   => `-5/18 + x= -8/18`

   => `x = -8/18 +5/18`

   => `x = -1/6`

   Vậy `x= -1/6`

   `3/4 – (x + 5/6) = -1/2`

   => `3/4 – x – 5/6 = -1/2`

   => ` -1/12 – x = -1/2`

   => `x = -1/12+ 1/2`

   => `x= 5/12`

   Vậy `x = 5/12`

2. `5/9 – (5/6 -x) = \frac{-8}{18}`
   `=> 5/6 -x = 5/9 – (-8)/18`
   `=> 5/6 – x = 1`
   `=> x = 5/6 -1`
   `=> x = -1/6`

   `3/4 – (x + 5/6) = \frac{-1}{2}`
   `=> x+5/6 = 3/4 – (-1)/2`
   `=> x + 5/6 = 5/4`
   `=> x = 5/4 – 5/6`
   `=> x =5/12`
