Answer 2

Resolver a equação quer dizer encontrar o valo da incognita de modo que a igualdade permaneça verdadeira.

$2x=8\\\\x=\frac{8}{2}\\\\ x=4$

--------------------------------------------------------------------------------------------------------------

$3x=24\\\\x=\frac{24}{3}\\\\ x=8$

-----------------------------------------------------------------------------------------------------------------

$x-17=-9\\\\x=-9+17\\\\x=8$

--------------------------------------------------------------------------------------------------------------$4x=36\\\\x=\frac{36}{4}\\\\ x=9$

--------------------------------------------------------------------------------------------------------------

$2x=-14\\\\x=\frac{-14}{2}\\\\ x=-7$
