  1. $\text{Lời giải}$
    $\text{x : 0,1 – x:4-x. $\frac{3}{4}$ = 2,25}$
    $\text{x:$\frac{1}{10}$ -x:4-x.$\frac{3}{4}$=2,25 }$
    $\text{x.10-x.$\frac{1}{4}$ -x.$\frac{3}{4}$ =2,25}$
    $\text{x.(10-$\frac{1}{4}$-$\frac{3}{4}$=$\frac{9}{4}$ }$
    $\text{x.9=2,25}$
    $\text{x=$\frac{1}{4}$ }$
    $\text{Vậy x=$\frac{1}{4}$ }$
