(2,1-0,7х):0,48=3,5,
(2,1-0,7х): $\frac{48}{10}$ = $\frac{35}{10}$ ,
(2,1-0,7х)* $\frac{100}{48}$ = $\frac{7}{2}$ ,
(2,1-0,7х)* $\frac{25}{2}$ = $\frac{7}{2}$ ,
2,1* $\frac{25}{12}$ -0,7х* $\frac{25}{12}$ = $\frac{7}{2}$ ,
$\frac{21}{10}$ * $\frac{25}{12}$ - $\frac{7}{10}$ х* $\frac{25}{12}$ = $\frac{7}{2}$ ,
$\frac{35}{8}$ - $\frac{35}{24}$ х= $\frac{7}{2}$ ,
24* $\frac{35}{8}$ -24* $\frac{35}{24}$ х=24* $\frac{7}{2}$ ,
3*35-35х=12*7,
105-35х=84,
-35х=84-105,
-35х=-21,
х= $\frac{21}{35}$ = $\frac{3}{5}$ .
Ответ: $\frac{3}{5}$
