  1. ~ Bạn tham khảo ~
    b, 49 + (104 – x) = 103
    => 104-x=103-49
    => 104-x=54
    => 104-54=x
    => x= 50
    Vậy x=50
    c, (x-34):12=25
    => x-34=25*12
    => x-34=300
    => x=300+34
    => x=334
    Vậy x=334

  2. b, 49 + ( 104 – x ) = 103
    104 – x = 103 – 49
    104 – x = 54
    x = 104 – 54
    x = 50
    c, ( x – 34 ) ÷ 12 = 25
    x – 34 = 25 × 12
    x – 34= 300
    x = 300 + 34
    x = 334
