1. 8/9 x – 2/3 = 1/3 x + 1 1/3

   => 8/9 x – 1/3 x = 4/3 + 2/3

   => (8/9 – 1/3)x = 2

   => (8/9 – 3/9)x = 2

   => 5/9 x = 2

   => x = 2 : 5/9

   => x = 2 . 9/5

   => x = 18/5

   Vậy x = 18/5

   8/9x-2/3=1/3x+11/3

   ⇔8/9x-2/3=1/3x+4/3

   ⇔(-1/3x)+8/9x=2/3+1/3

   ⇔5/9x=1

   ⇔x=1÷5/9

   ⇔x=9/5

   $\text{Vậy x}$=9/5
