  1. ~ Bạn tham khảo ~
    5 8/17÷x+(-4/17)÷x+3 1/7÷17 1/3=4/11
    => (5 8/17 – 4/17) ÷ x + 33/182 = 4/11
    => 89/17 ÷ x = 4/11 – 33/182
    => 89/17 ÷ x = 365/2002
    => 89/17 ÷ 365/2002 = x
    => x = 178178/6205
    Vậy x=178178/6205

  2. 5(8)/(17):x+(-4/(17)):x+3(1)/(7):17(1)/(3)=4/(11)
    ⇔(5(8)/(17)-4/(17)):x+(33)/(182)=4/(11)
    ⇔(89)/(17):x+(33)/(182)=4/(11)
    ⇔(89)/(17):x=(365)/(2002)
    ⇔x=(178178)/(6205)
    Vậy x=(178178)/(6205)
