  1. $#mind$
    3(x + 6) – 5³= 2(x – 8) – 1
    3x + 18 – 125 = 2x – 16 – 1
    3x – 107 = 2x – 17
    3x – 2x = – 17 + 107
    x = 90
    Vậy x = 90
    Xiin ctlhn+5*+cảm ơn:3
    Chúc bé thi học kì đạt kết quả cao nhé ^^

  2. 3(x+6)-5^3=2(x-8)-1
    3x+18-125=2x-16-1
    3x-107=2x-17
    3x-2x=107-17
    ⇒x=90
    Vậy x=90
