  1. $\text{x × 4,9 + x : 10 = 10,5}$
    $\text{x × 4,9 + x × 0,1 = 10,5}$
    $\text{x × ( 4,9 + 0,1 ) = 10,5}$
    $\text{x × 5 = 10,5}$
    $\text{x = 10,5 : 5}$
    $\text{x = 2,1}$
    $\text{Xin hay nhất và 5 sao ạ}$
     

  2. @Bao
    x xx 4,9+x:10=10,5
    ->x xx 4,9+x xx0,1=10,5
    ->x xx (4,9+0,1)=10,5
    ->x xx 5=10,5
    ->x=10,5:5=2,1
