Me ayudan 8,1( )=21,31.

¡Hola!

$\bold{ECUACI \acute{O}N.}$

$8.1( \: \: ) = 21.31 \\ \\ \\ 8.1x = 21.31 \\ \\ \\ \dfrac{8.1x}{ \green{8.1}} = \dfrac{21.31}{ \green{8.1}} \\ \\ \\ \mapsto \boxed{ \boxed{ \pink{x =2.631}}}$

El valor es 2,631.

$\bold{VAMOS \ A \ COMPROBAR.}$

$8.1( \: \: ) = 21.31 \\ \\ \\ 8.1( \purple{2.631}) = 21.31 \\ \\ \\ 21.31 = 21.31$

Espero que sirva y saludos.
