  1.  (2x + 1) . 2907 = 8721
     2x + 1 =  8721 : 2907
    2x + 1 = 3
     2x = 2
      x = 1
    vậy x = 1 

  2. Answer
    (2x + 1) . 2907 = 8721
    $\Rightarrow$ (2x + 1) = 8721 : 2907
    $\Rightarrow$ 2x + 1 = 3
    $\Rightarrow$ 2x = 3 – 1
    $\Rightarrow$ 2x = 2
    $\Rightarrow$ x = 2 : 2
    $\Rightarrow$ x = 1
    $\text{Vậy}$ x = 1
