  1. $#AS$
    x xx 3 + x xx 14 = 35,7
    x xx (3 + 14)      = 35,7
    x xx 17              = 35,7
    x                       = 35,7 : 17
    Vậy x                = 2,1

  2. Answer
    x xx 3 + x xx 14 = 35,7
    x xx (3 + 14) = 35,7
    x xx 17 = 35,7
    x = 35,7 : 17
    x = 2,1
    $\text{Vậy}$ x = 2,1
