  1. ~ Bạn tham khảo ~
    y xx 8,01 – y : 100 = 38
    y xx 8,01 – y xx 1/100 = 38
    y xx (8,01 – 1/100) = 38
    y xx 8 = 38
    y = 38 : 8
    y = 19/4
    y = 4,75
    Vậy y = 4,75

  2. y x 8,01 – y/100 = 38
    y x 8,01 – y : 100 = 38
    y x 8,01 – y x 0,01 = 38
    y x ( 8,01 – 0,01 ) = 38
    y x 8 = 38
    y = 38 : 8
    y = 4,75
    Vậy y = 4,75
