  1. $\text{(x-4):2+11=23}$
    $\text{⇒(x-4):2=23-11}$
    $\text{⇒(x-4):2=12}$
    $\text{⇒x-4=12·2}$
    $\text{⇒x-4=24}$
    $\text{⇒x=24+4}$
    $\text{⇒x=28}$
    $\text{Vậy x=28}$

  2. (x  – 4) : 2 +11 = 23
    ⇒(x  – 4) : 2 =23-11
    ⇒(x  – 4) : 2 =12
    ⇒x  – 4=12×2
    ⇒x-4=24
    ⇒x=24+4
    ⇒x=28
