  1. ~ Bạn tham khảo ~
    a, 9,5 xx x = 47,4 + 24,8
    9,5 xx x = 72,2
    x = 72,2 : 9,5
    x = 7,6
    Vậy x = 7,6
    b, x : 8,4 = 47,04 – 29,75
    x : 8,4 = 17,29
    x = 17,29 xx 8,4
    x = 145,236
    Vậy x = 145,236

  2. a) 9,5×x=47,4+24,8
    9,5×x=72,2
    x=72,2:9,5
    x=7,6
    b) x:8,4=47,04-29,75
    x:8,4=17,29
    x=17,29×8,4
    x=145,236
