  1. Answer
    71 – (33 + x) = 26
    => 33 + x = 71 – 26
    => 33 + x = 45
    => x = 45 – 33
    => x = 12
    $\text{Vậy}$ x = 12

  2. $\text{71 – (33 + x) = 26}$
    $\text{⇒ 33 + x = 71 – 26}$
    $\text{⇒ 33 + x = 45}$
    $\text{⇒ x = 45 – 33}$
    $\text{⇒ x = 12}$
    $\text{Vậy x = 12}$
