  1. a)
    x – 103 = -203
    x              = ( -203 ) + 103
    x              = -100 
    b)
    x + ( -36 ) = 0
    x                       =  0 – ( -36 )
    x                       = 36
    c)
    x – 105 = -150
    x               =  ( -150 ) + 105
    x               = -45
    d)
    x – 21 = -29
    x            =  ( -29 )  + 21
    x            =  -8

  2. ~ Bạn tham khảo ~
    a) x – 103 = (-203)
    x = (-203) + 103
    x = -100
    Vậy x = -100
    b) x+(-36) = 0
    x = 0 – (-36)
    x = 0+36
    x = 36
    Vậy x = 36
    c)  x-105 = -150
    x = (-150) + 105
    x = -45
    Vậy x =-45
    d) x – 21= -29
    x = (-29) + 21
    x = -8
    Vậy x =-8
