  1. x – 6 : 2 . (42 – 24 . 2 : 6 – 3) = 0
    $\Rightarrow$ x – 6 : 2 . (42 – 48 : 6 – 3) = 0
    $\Rightarrow$ x – 6 : 2 . (42 – 8 – 3) = 0
    $\Rightarrow$ x – 6 : 2 . (34 – 3) = 0
    $\Rightarrow$ x – 6 : 2 . 31 = 0
    $\Rightarrow$ x – 3 . 31  = 0
    $\Rightarrow$ x – 93  = 0
    $\Rightarrow$ x = 0 + 93
    $\Rightarrow$ x = 93
    $\text{Vậy}$ x = 93

  2. x-6:2(42-24*2:6-3)=0
    ⇒ x – 6/2(42 – (24 * 2)/6 – 3) = 0
    ⇒ x – 6/2(42 – 48/6 – 3) = 0
    ⇒ x – 6/2(42 – 8 – 3) = 0
    ⇒ x – 6/2(34 – 3) = 0
    ⇒ x – 6/2 * 31 = 0
    ⇒ x – 3 * 31 = 0
    ⇒ x – 93 = 0
    → x = 93
