    a) x – 5 = – 1
    x=-1+5
    x=4
    Vậy x=4
    b)x + 30 = – 4
    x=-4-30
    x=-34
    Vậy x=-34
    c) x – (- 24) = 3
    x=3+24
    x=27
    Vậy x=27
    d)22-(-x)=12
    22+x=12
    x=12-22
    x=-10
    Vậy x=-10

    $\text{a) x – 5 = -1}$
    $\text{x = ( -1 ) + 5}$
    $\text{x = 4}$
    $\text{Vậy x = 4}$
    $\text{b) x + 30 = -4}$
    $\text{x = ( -4 ) – 30}$
    $\text{x = -34}$
    $\text{Vậy x = -34}$
    $\text{c) x – ( – 24 ) = 3}$
    $\text{x + 24 = 3}$
    $\text{x = 3 – 24}$
    $\text{x = – 21}$
    $\text{Vậy x = -21}$
    $\text{d) 22 – ( – x ) = 12}$
    $\text{22 + x = 12}$
    $\text{x = 12 – 22}$
    $\text{x = -10}$
    $\text{Vậy x = -10}$
